Barcelona president Joan Laporta is convinced Ronaldinho will again be at "his best" before the end of the season.
"He is more motivated than ever before. He is working very hard to return as soon as possible. The reports we have from the coaches and medical people is that he is in great shape."
He added: "I believe that when one suffers an injury, you usually lose form. So, of course you gain weight and you need a period of recovery to get back in shape, which is precisely what he is doing now."
