Probable starting eleven:Atletico Madrid:Courtois, Juanfran, Miranda, Godin, Luis, Rodriguez, Gabi, Tiago, Koke, Villa, Garcia Barcelona:Pinto, Alves, Mascherano, Bartra, Alba, Xavi, Busquets, Iniesta, Fabregas, Messi, NeymarThe first match at Nou Camp finished with a 1:1 draw and Atletico Madrid now have a huge advantage. Even a goalless draw is good enough for them to secure the semi-final. However, it won’t be easy as Barcelona are one of the strongest sides in Europe.I believe this match will finish with draw. Barcelona are stronger and they are closer to the victory. Even more as the hosts are weakenned with the potential absence of the key striker Diego Costa. He got an injury on the first match and skip the Saturday match in La Liga against Villarreal. Diego Costa is rated as doubtful, but I don’t believe the coach Diego Simeone will risk with him.So, Barcelona are stronger, they have the key players like Messi, Xavi and Iniesta ready for this match. The coach Tata Martino has some unavailable players too as Jonathan dos Santos, goalkeeper Victor Valdes, Gerard Pique and Isaac Cuenca are out injured, while Carles Puyol is doubtful. The last four mutual matches between Barcelona and Atletico Madrid were have ended with draw. Here are the results:01.04.2014. Barcelona – Atletico Madrid 1:111.01.2014. Atletico Madrid – Barcelona 0:028.08.2013. Barcelona – Atletico Madrid 0:021.08.2013. Atletico Madrid – Barcelona 1:1I expect another draw.
