Barcelona ace Xavi has heaped praise on teammate Sergio Busquets.

Coach Pep Guardiola declared Busquets the best defensive midfielder in the world.

And Xavi concurs: "He should have been in the FIFPro World XI. He's an extraordinary player and he rarely makes a mistake either in attack or defence.

"He gives us balance and is key to our system. He's more valued by his fellow professionals than by the media."
