Juventus CEO Giuseppe Marotta has promised the club will do everything they can to keep hold of Paul Pogba but admits they will inevitably struggle to match the wages Europe's elite will be able to offer him.

The ex-Manchester United starlet remains linked with a return to Old Trafford, while Chelsea, Real Madrid and Paris Saint-Germain are also credited with interest in the Frenchman who has grown into one of the most coveted young players in Europe.

Speaking in January, Pogba's agent Mino Raiola claimed the 21-year-old will leave Turin when the time is right and, despite the club's best intentions, Marotta admits financial limitations are likely to pave the way for his exit.

"In reality, we will do everyone to keep Pogba," Marotta was quoted as saying by Italian outlet Tutto Mercato.

"The problem will be the salaries that he will be offered [by other clubs]. It might not be compatible with our league but for the moment we are not selling him."

In October, Pogba signed a new contract with Juventus, which will keep him with the Serie A champions until 2019.

But his new deal has done little to dampen speculation regarding his future.

Any decision to cash in on the France international is likely to prompt a bidding war among Europe's elite clubs for the midfielder, with his former club United still a possibility it would seem despite his acrimonious departure from Old Trafford in 2011.

Speaking to FourFourTwo, Pogba said: "I am impatient. It was the feeling I had. The coach [Sir Alex Ferguson] had faith in me but didn't put me on. He said I was too young.

"He said: 'Your time will come,' but it never did. It didn't come. But it does not mean I will speak ill of Manchester United. I love the club."
