Whither Ronaldinho

He was once a lean mean goal machine .Now he barely gets off the bench.He came in as a substitute and helped Barcelona close the gap with Real Madrid by scoring a penalty in their 2-1 win against Real Zaragoza ( Video here )Opinions vary.Andreas Hinkel is telling his Celtic teammates not to be taken in by the weighty reputation of Barcelona, if they want to progress in the Champions League. He picked out the decline of Ronaldinho as an example of how " the pursuit of excess, rather than success, has made the Spanish side vulnerable."
An opposite opinion from Eidur Gudjohnsen.He insists that Ronaldinho ( still) is the best player he has ever worked with.
