Ex-referee claims Suarez deserved a red card for the foul on Nacho

Ex-referee and Marca's expert Andujar Oliver has had his say on the second half incident when Luis Suarez stepped on Nacho's leg: "It's an error of Sanchez Martinez because it's an action that should have been a red card. It's a clear stamp on the Real Madrid defender."

On the penalty, which helped Barcelona double their lead in the first half, Andujar Oliver said: "It was a clear penalty."
