Barcelona and Argentina star Lionel Messi visited a Buenos Aires hospital on Thursday where he had a scan on the muscle injury in his right leg that has kept him out of action for over a month.

Donato Villani, doctor with the Argentina national team, said he was pleased with the progress of the 18-year-old.

"The injury is progressing well but we can not set a date for his return because that would put extra pressure on him," said Villani.

Barcelona's doctors have been in charge of the treatment, according to Villani, who said: "This guy is in Barcelona's hands. The only thing we did is to help Barcelona's medical staff during their stay in Buenos Aires.

"We're in permanent contact with them so it won't be necessary for us to go to Spain to see Lionel."

Barca hope he will be fit for the Champions League final with Arsenal in Paris on May 17.
