Real Madrid captain Iker Casillas is expecting a backlash from Barcelona when the two meet again in the league on Saturday after Madrid's 3-1 victory over the Catalans on Tuesday.
.
The Spanish champions booked their place in the Spanish Cup final with a complete performance that restricted Barca to very little going forward and contained their usual lightning speed on the counter- attack.
.
But Casillas believes he knows many of his international colleagues in the Barca side too well to think they will take defeat lying down.
.
"I know many of the Barcelona players and I know that they are competitive," he told the club's website.
.
Despite their joy in the cup, in the league it is Barca who have been the dominant force this season as they arrive in the capital with a 16-point advantage over Real.
.
And with another huge Champions League game to come against Manchester United on Tuesday, many expect Jose Mourinho to make a number of changes.
.
However, Casillas believes it is important to try and maintain their positive momentum heading into their trip to Old Trafford with the teams locked 1-1 after the first leg of their last-16 duel.
I see a 1-1 draw at the end of 90 minutes.
