Barcelona defender Gerard Pique is convinced there's tension inside the Real Madrid locker room.

Pique believes Jose Mourinho is struggling to keep a lid on things at Real.

"With Real Madrid there is not the tension with us that was there last season. Mourinho has realized that he does not have to look for anything in Barcelona because you will not find anything and so he is looking at home," said Pique.

"When you are behind in the standings, people do not get along so well. Last season was the example, it took its toll on us."
