Paul Pogba vowed to keep giving his all “no matter what’s going on” after his starring role in Manchester United‘s season-opening win over Leicester.

The midfielder, a World Cup winner with France, has been the subject of speculation in recent days concerning both a possible transfer to Barcelona and his relationship with manager Jose Mourinho.

He was handed the captain’s armband against the Foxes and set United on their way to a 2-1 victory with an early penalty – but appeared to allude to off-field issues in a post on his social media accounts after the game.

Pogba wrote: “I’ll always give my best to the fans and my teammates no matter what’s going on. #pogfeelings”.

While the Premier League transfer window closed on Thursday evening, clubs elsewhere in Europe can still buy players until the end of August and reports of a move to Barca have persisted.

Mourinho hailed Pogba’s “monster” performance after the game but also once more referenced United’s lack of signings this summer, saying: “I find myself with the market closed in a situation I did not think I would be in.”
