Jose Mourinho  has confirmed Fernando Torres  is fit and ready to return for Chelsea 's Champions League game at Basel on Tuesday.The Spain international has been out of action since being substituted in a 2-0 defeat at Newcastle United on November 2 due to an abductor muscle injury.However, Torres travelled with the Chelsea squad for the Group E clash at St Jakob Park, with coach Mourinho subsequently revealing that the striker is available for selection."Torres is ready to play. He trained with the team yesterday [Sunday] and this morning with no limitation and he is ready to play," the Portuguese told reporters on Monday.Chelsea have surged to the top of the group, collecting nine points from three games since their shock 2-1 defeat to Basel at Stamford Bridge on matchday one.While Mourinho accepts the Swiss champions - who currently lie third in the pool - deserved to win that match, he has urged his side to focus on securing qualification for the knockout stages by gaining revenge on Tuesday."Basel are a good team. They won in London because they played better than us (but) we are in a better situation now," he added."If somebody tomorrow [Tuesday] has to feel the pressure it's not us, it's Basel. We can finish the job to qualify. After the first match, we did our job."Mourinho also admitted he has found it difficult to omit Juan Mata from his starting line-up, but insists there is nothing personal behind the Spaniard's exile."I can't change the rules, I can't start the match with 12, 13 or 14 players," he continued. "Juan deserves to play."'I have to leave players out because I can't start with 15 players. It's a good problem because I have so many good options."
