Atletico Madrid striker Diego Costa expects Chelsea will play with a more attacking style in the second leg of the Champions League semi-final after their draw 0-0 at the Vicente Calderon last week.

The Spanish press heavily criticised Jose Mourinho's approach in their first encounter as he opted to 'park the bus' to avoid conceding any goals, leaving the Blues well placed ahead of the return leg at Stamford Bridge.

The Chelsea boss used similar tactics as his side beat Liverpool 2-0 in their Premier League clash on Sunday but Costa believes Atletico's opponents will change their style on Wednesday as they will need to win the game to reach the final.

"I think that the game at Stamford Bridge will be a little different than the one they played in our house. I believe they have to get out more (from the area) but if they do not do it we will look for the best way to beat them because we have the potential to make something big," Costa was quoted by Mundo Deportivo.

While Mourinho used four midfielders in the first tie – David Luiz, Frank Lampard, Obi Mikel and Ramires – he will have to pick from more offensive players on Wednesday game as Lampard and Mikel are suspended with Marco Van Ginkel having only recently returned from long term injury.

Earlier this month reports in Spain claimed that Diego Costa will move to Chelsea at the end of the season, encouraging Chelsea supporters to chant his name during the first leg.

When asked about that, Costa said: "I did not understand anything. They said my name but I was not worried about that in that moment. I am very pleased and happy at Atletico."
