Celtic could lose defender Kieran Tierney this summer with Manchester United keen on procuring his signature, reports the Mirror.

The 20-year-old has been a star performer under Brendan Rodgers, winning two Scottish Premiership titles, two Scottish League Cups and one Scottish Cup but his future is uncertain.

Arsenal, Tottenham and Manchester United are three clubs who have been linked with the Scotland international, but the Bhoys may not budge for anything less than £25m.

Arsenal are eyeing up a replacement for the ageing Nacho Monreal, Tottenham want Tierney if they lose Danny Rose and United want the Celtic man as a replacement for Luke Shaw.

A bidding war could commence this summer, but Celtic would ideally prefer to keep the irreplaceable Tierney. He’s made 27 league appearances this season, scoring and creating nine goals.

The Mirror say United are leading the race for his signature as they consider Tierney a much cheaper option than the likes of Rose and Juventus’ Alex Sandro.

The Celtic left-back hasn’t made a public desire to leave, however, so there’s a slim chance he could stay at Parkhead for another year. Tierney’s deal runs until 2023 so Celtic are in no rush to sell.
