Manchester United could reportedly attempt to sign Barcelona attacker Antoine Griezmann in a "bargain" deal during this summer's transfer window.

The France international could allegedly be available for transfer ahead of the 2019-20 campaign, and United have recently been credited with an interest in his services.

According to journalist Duncan Castles, Barca's desire to sell the 2018 World Cup winner could lead to the Red Devils exploring the possibility of signing the former Atletico Madrid attacker for a cut-price fee.

"Griezmann turned 29 last month so he's at that point in his career where your valuation and your worth in the transfer market goes down inevitably," Castles said on the Transfer Window podcast. "You have to find another club who is prepared to take him. Everyone knows that Barcelona are in difficult financial situations.

"Everyone knows that the dressing room didn't want Griezmann to come in the first place and want him out now and that Barcelona are looking for a replacement.

"So all of those things reduce his value and that's why I think you will see a club like Manchester United, who tried to sign Griezmann in the past and value him as a player, value him as a commercial asset as well, that's part of their thinking in trying to sign him two years ago, say: 'Well let's just have a look at this and see if there is a serious bargain to be had'.

"'How far can Barcelona be pushed? Who else is interested in taking the player? How much competition is there on the market? 'And maybe we can get someone we were prepared to spend the majority of our transfer budget on two years ago at a fraction of that cost and if that is the case, perhaps that's a better route to go down than the one we'd originally been playing'."

Griezmann, who has a contract at Camp Nou until the summer of 2024, has scored 14 times in 37 appearances for Quique Setien's side during the current season.
