Dunga: Barcelona ace Ronaldinho must work harder

He said on Catalan Radio: “Kaka is the best player at the moment. Ronaldinho has the capability to return to the top, and Robinho could be up there too.”

“Ronaldinho lacks pace. He does not have that 30 or 40 metre burst that he used to have last season, which used to help him get away from defenders.

“He must train more. When he is physically perfect, Ronaldinho is unstoppable. As he was last season.

“Technically, he is superior to the rest.”
