Real Madrid coach Carlo Ancelotti insists Iker Casillas will play in the El Clasico against Barcelona.

Ancelotti went with Keylor Navas for yesterday's victory over Levante.

Asked about Sunday's trip to Barcelona, Ancelotti says "Casillas will certainly play".

Sections of the Madrid press believe Ancelotti is more comfortable playing Casillas away from the Santiago Bernabeu. The club captain was again whistled by home fans yesterday, despite being on the bench.

Upon his name being announced amongst the substitutes before kickoff, Casillas was again jeered by sections of the Bernabeu support.
