Despite clear indications from Barcelona that Cesc Fabregas is not for sale, his team-mate Javier Mascherano has been unable to unequivocally rule out a move to Old Trafford for the midfielder.
The Independent reported earlier this month that Fabregas' head had been turned by the attention from Manchester United, particularly in light of his frustrations since moving to the Nou Camp from Arsenal two years ago.
New Barca head coach Gerardo Martino appeared to end all talk of a big money move when he insisted the 26-year-old would not be sold, but Mascherano is not certain the deal is dead, despite insisting he believes his team-mate is happy in Spain.
"I didn't talk to him, but he's happy," Mascherano told Fox Sports Asia.
"It's difficult when you have to talk about the personal situation of other players because sometimes you don't know what they really think.
"But I could see him here training and he's happy. He grew up in Barcelona and he feels the colours of the shirt.
"It's difficult when you grew up here to leave because Barcelona is a big team and a big city, where it's really nice to live and his family is here."
Defensive midfielder Mascherano, who usually plays at centre-back for Barca, could not completely rule out Fabregas making a switch to Old Trafford before the transfer window closes on September 2.
"I don't know," the Argentinian added. "You can never say no but at the moment I think he is a really good player for us and the coach and the people that work here want to keep him."
Fabregas' former Arsenal team-mate Alex Song, however, was more certain in his belief that the Spaniard would stay at the Nou Camp for the foreseeable future.
The Cameroonian told sport.es before a friendly game against Legia Gdansk: "I know him well and everything that's been talked about is just speculation. He loves the club and the city and I think he wants to continue with Barca."
