Manchester United have reportedly been put on alert to the potential availability of Juventus winger Douglas Costa.

The 29-year-old has been touted as a possible alternative for Jadon Sancho, who remains United's top transfer target but whose £108m asking price is deemed too high by the club's hierarchy.

Goal reports that Juventus have now lost patience with Costa due to his recent injury problems and would be open to offers for him this summer.

New Juve boss Andrea Pirlo has already undergone a significant overhaul of his squad since taking over, with Gonzalo Higuain, Miralem Pjanic, Sami Khedira and Blaise Matuidi - all of whom are over the age of 30 - being shipped out.

Costa missed a large chunk of last season through injury and will miss the beginning of the new campaign too.

The winger, who has two years left on his contract at the Allianz Stadium, remains keen to stay in Turin and prove his worth to Pirlo.

In addition to United, clubs in the UAE Pro League are also thought to be considering a move for Costa, although his injury record is causing hesitation among potential suitors.

Costa has only made 40 Serie A appearances over the past two seasons, scoring four goals and creating eight more in that time.

Kylian Mbappe 'wants to leave PSG, interested in Manchester United, Liverpool',format&fit=clip

Kylian Mbappe has reportedly informed Paris Saint-Germain that he wants to move to another club in the future.

Due to the financial implications of the coronavirus pandemic, none of European football's top clubs can currently afford a world-record bid for the France international

PSG sporting director Leonardo has acknowledged that he will look to take advantage of the situation by offering Mbappe a contract extension, tying the World Cup winner to the Ligue 1 champions past 2022.

However, according to The Times, the 21-year-old has his sights set on a transfer to a club in the Premier League or La Liga.

The report suggests that Mbappe is open to the idea of signing for Liverpool or Manchester United, while speculation regarding a potential switch to Real Madrid will not go away.

Despite the prospect of lower offers being made next summer, PSG are unlikely to agree to a sale over the coming weeks.
