Barcelona presidential front-runner Sandro Rosell has admitted he would consider controversially selling shirt sponsorship for the first time in the club's 111-year history.

The former Barca vice-president, who left the club in 2005 following a falling out with current supremo Joan Laporta, will stand for election this summer and is already regarded as the strong favourite.

Rosell is unwilling to discuss his campaign until officially announcing his plans in May.

"We're not at election time," he said.

However, he spoke about the hot topic of shirt sponsorship which may displease some supporters of the club.

Barca were one of the last remaining major clubs in the world to resist the lure of bearing logos on their famous 'Blaugrana' colours.

However, Laporta put advertising on the shirt for the first time in 2006 as a humanitarian gesture to UNICEF, even paying around 1.5million euros for the privilege.

Rosell revealed he would consider combining that with a money-making sponsorship deal should economics demand it.

"Everything depends on the club's finances," he said.

"First you have to see how the club is economically and subsequently make decisions.

"If you do not know the numbers, you cannot give a very honest view."

Rosell also spoke about his desire to see a salary cap introduced in football, despite the obvious difficulties enforcing it.

"I would like to see some form of structure, economically," he said.

"The best way would be to have fixed amounts with incentive-based bonuses for good results. I think that would be the best way to cap wages."
