Everton boss Roberto Martinez has hailed the quality of Manchester United midfielder Ander Herrera.

Martinez will go up against an in-form Herrera when his side take on Manchester United tomorrow at Goodison Park.

He said: "It has been mentioned many times about him replacing one of the big midfielders that Spain have had over the years -Xabi Alonso, Xavi Hernandez, Iniesta.

"He is someone that is ready to do that, but obviously the amount of footballers you have got in that position in Spain is huge.

"I think Ander Herrera is someone who will always find a way to be successful so I wouldn't put it past him."
