The agent of Manchester United target Bruno Fernandes has said he is not sure whether the Portugal international will move to Old Trafford this January.
Sources had told ESPN that United agreed personal terms with Fernandes over a move in this transfer window. However, failure to agree a fee with Sporting could lead United to walk away from a deal, according to ESPN sources.
And agent Jorge Mendes said that, while his client will leave Sporting, he cannot say for certain whether that will be now or at the end of the season.
"I don't know what will happen with Bruno Fernandes," he told Sky Sports. "If he doesn't leave now, for sure he will leave in summer."
Meanwhile, Paul Pogba's agent Mino Raiola would not be drawn on the France international's future, as he recovers from ankle surgery.
"For now he needs to be getting fit and then it's my job to try to get both parties [player and club], if possible, happy," Raiola told Sky Sports. "He [Pogba] went back to United when lot of people didn't think he would.
"People forget that. He chose Manchester United. Let's address the elephant in the room -- everyone knows the ambitions of the club have not been met in the last few years, let's be honest."
Asked about his relationship with United having told La Repubblica in December he would stop doing business with the club, Raiola added: "It's good. It's a professional, honest, relationship.
"I've never spoken to Ole [Gunnar Solskjaer], but my relationship with Ed [Woodward] is transparent."
