Chelsea are reportedly interested in activating Giovani Dos Santos' £13.5million buy-out clause.
The Barcelona forward enjoyed an impressive pre-season with the club this summer and chose to remain at Camp Nou rather than move to Mexican club Chivas on loan.
However, the Mexican forward faces stiff competition to break into the first-team this season, with the 'Fantastic Four' - Ronaldinho, Samuel Eto'o, Lionel Messi and Thierry Henry - currently ahead of him in the pecking order.
With a dangerously low buy-out clause, Barca chiefs are now keen to tie down the wonderkid on a long-term contract.
However, Dos Santos explained that negotiations are ongoing, and reiterated the competition he faces in breaking into the starting line-up.
"I haven't signed - we're still talking," Dos Santos told The Sun.
"With so many stars at Barcelona, sometimes I think it would be good if football was played with 12 as that way I wouldn't be left out."
The 18-year-old has also been called into the Mexico squad for their forthcoming friendlies against Panama and Brazil, but head coach Hugo Sanchez has pleaded with fans not to pile pressure on the youngster.
"We have to take it easy, we mustn't pressure him or put too much responsibility on his shoulders, instead we must motivate him and take away the weight of responsibility," Sanchez explained.
