New Real Madrid coach Jose Mourinho says Chelsea ace Frank Lampard stacks up well with Barcelona stars Xavi and Andreas Iniesta.

Mourinho was asked who he believed was the world's best midfielder.

He said: "It's difficult to choose who the best is because they play in different football cultures.

"You can't say that (Chelsea's Frank) Lampard will score 30 goals in Serie A or in the Primera Division but in England he averages 28 goals per season, which is incredible.

"You cannot say either that (Barcelona pair) Xavi or Andres Iniesta will perform with the same quality if they were to go to the Premier League or Serie A."
