MADRID, June 4: Brazil forward Ronaldinho has been told by his national coach Dunga to improve his fitness levels if he wants to regain the mantle of the world's best player.

“Kaka is the best player at the moment, Ronaldinho has the capability to return to the top and Robinho could be up there,” Dunga was quoted as telling Catalunya Radio in the Spanish media on Monday.

“Ronaldinho lacks pace at present. He lacks that initial burst of speed that allows him to get away from rivals.”

The 27-year-old Barcelona player has been criticised by fans and the Spanish media for being overweight, out of shape and missing training sessions during the Primera Liga season.

Although he has been inconsistent, he is the side's top scorer with 20 goals.

“He has to train more. A Ronaldinho at peak fitness is impossible to stop as seen last year. Technically he is better than the rest,” Dunga added.—Reuters
