As Rafael Nadal targets another title at the Barcelona Open, we asked Barry Cowan five key questions about the clay court tournament.The Spaniard made a triumphant start to this years clay campaign when he took the trophy at last weekends Monte Carlo Masters, beating Gael Monfils in the final.An impressive semi-final victory over Andy Murray was further evidence of Nadals improved form, but can he claim back-to-back titles in Barcelona, where Kei Nishikori is the defending champion? Are we watching Rafas revival? Nadal defeated Gael Monfils in the final of the Monte Carlo Masters I felt that first set between Rafa and Dominic Thiem was the biggest difference. Nadal saved 15 of 16 break points and the way he saved them - he was not playing with any fear. Nadal was playing with a lot of confidence and it was reminiscent of Rafa at his best.After that first set, he didnt look back. When you come through those moments it gives you a lot of self-belief. When he was set down against Andy Murray, or lost the second set to Gael Monfils, he moved on quickly and got on with the task. That is one of Rafas best attributes.Is Nadal the man to beat? The Spaniard has dominated the clay court campaign in past years Traditionally once Rafa builds momentum then he never looks back. He had the advantage last week of Novak Djokovic losing. I think he had to win a tournament like that, once Djokovic was no longer standing in the way.Again this week, Rafa must play with the same freedom, back himself, and I do expect him to do that. Rafa still has got great tennis in him and its amazing, even in two or three matches, how your aura can switch around.Can Kei ruin Rafas run? Kei Nishikori was beaten by Novak Djokovic in the final of the Miami Masters Kei played great in Miami. That match with Monfils was certainly one of the best matches that I saw during those two weeks.Given how well Gael played last week in Monte Carlo, it really shows Keis form at the moment. He is an exceptional player on clay and will be there or thereabouts. Nishikori will be hoping to kick-start his clay court season.Best of the rest in Barca? David Ferrer pulled out of the Monte Carlo tournament due to injury It will be interesting to see how third seed David Ferrer performs. Obviously he missed last week in Monte Carlo. Its a big week for him, because he needs to rack up some points, otherwise he will be going in the wrong direction.Benoit Paire gave Andy Murray a real scare last week, but he will continually flatter to deceive. One of the most talented players out there and at times he looks like a world-beater, but then in the flick of a switch, he can self-destruct.Important step towards Paris? Nadal will be seeking a 10th title at the French Open This is another key tournament for players to prepare for the French Open. Is Rafa able to play at that high level for two weeks running? When Rafa was at his best, it was a given. I was incredibly impressed with Rafa, but he needs to show that same form coming into this week.Hes the main man to be shot at and its something he has coped well with over the years. It will be fascinating to see how he performs.Watch live coverage of the Barcelona Open on Sky Sports this week.Also See:Sky Live: Barcelona OpenNadal claims Monte Carlo titleMurray: Best man wonRafa beats Murray in Monte CarloCheap Air Max .

Three came down to the fourth quarter while quarterbacks continued to shine in all four games; so important to the overall quality of the game.PITTSBURGH -- Pittsburgh Steelers defensive coordinator Keith Butler only wishes he was brilliant enough to explain how a defense that struggled to get to the quarterback for two months seemed to have little trouble last Sunday in Cleveland.The same group that managed all of 13 sacks through nine games piled up eight in four dominant quarters against the inept Browns.And heres the thing, Butler figures the number should have been closer to a dozen. So what was it? Scheme? A return to the teams Blitzburgh roots? Savvy coaching? Butler wishes he could take the credit. He cant.If I knew that Id do it every week, Butler said Tuesday. We got after `em a little bit, but at the same time we executed better.Playing the NFLs worst team helped. Yet the Steelers (5-5) believe theres a little more to it. Butler moved defensive end Stephon Tuitt up and down the defensive line, rarely putting him in the same spot on consecutive snaps.Inside linebacker Ryan Shazier was given more freedom to get into the backfield -- sometimes lining up on the outside in search of a mismatch -- and Butler even allowed rookie safety Sean Davis to cause havoc.And Pittsburgh did it with its best defensive player back home dealing with a torn pectoral muscle that ended his season.Watching instead of playing will take some getting used to for Cam Heyward, though hes adjusting to the role of head cheerleader rather quickly.After watching Tuitt pick up 2+ sacks and rookie nose tackle Javon Hargrave belly flopping on a fumble for a touchdown, Heyward issued a well-intentioned dare heading into Thursday nights visit to Indianapolis (5-5), where journeyman quarterback Scott Tolzien appears ready to fill in for the injured Andrew Luck.I challenged them to do it again this week, Heyward said. Now youve seen what you can do, lets keep it going. Lets keep accomplishing goals.The Steelers may have caught a break with Luck unlikely to play while going through the leagues concussion protocol.If Luck sits, that means Tolzien will be the one playing behind an offensive line thats given up 35 sacks, the second-highest total in the NFL even with the mobile Luck under center.Weve had our issues in the past as far as sacks aand pressures and things like that, Colts coach Chuck Pagano said.ddddddddddddTheyve got a great unit and a great defense coming. We all saw what they did against the Browns and what theyre capable of.And thats kind of been the problem this season for the Steelers, who piled up 48 sacks during Butlers first year as coordinator in 2015, but have failed to create any consistent kind of havoc in the pocket so far in 2016.Initially Butler opted to play it safe while incorporating a slew of new faces into the lineup.Yet even when he started to mix it up in later weeks -- particularly during a four-game losing streak that took all the momentum out of Pittsburghs 4-1 start -- plays that were out there to be made were not.My thing with them is just do your job (and) stop trying to do someone elses job, Butler said. Thats usually what happens when you have a breakdown is you try to overcompensate for what you think is a weakness in the defense instead of just doing your job.The tape from Cleveland showed the message may finally be getting through.Its definitely a game we can build on, Shazier said. We understand we take care of our responsibilities then everything will be taken care of. Guys understand if we do our job, the plays coming our way are going to happen instead of trying to force something.Tolzien hasnt taken a meaningful snap since subbing for Aaron Rodgers in Green Bay in 2013. While Pagano stressed Tolzien knows the Indianapolis offense inside and out, he also hasnt been hit when it matters for three years.A little chaos may go a long way for the Steelers as they try to go on another second-half run similar to the ones that carried them to the postseason in 2014 and 2015.We know were capable of more, Davis said. Its just about staying aggressive and paying attention to details.Game notesWR Darrius Heyward-Bey (foot) and RB DeAngelo Williams (knee) are likely out. ...
