Manchester United stars showed off their new blue suits for Saturday's showpiece FA Cup final clash with Manchester City.

Casemiro, David De Gea and Antony, among others all posed for photos in their smart new Paul Smith-designed outfits. 

The designer has been kitting out United's stars since 2008 and their partnership is still going strong.

Anthony Elanga, Aaron Wan-Bissaka, Alejandro Garnacho and Diogo Dalot - who has signed a new contract extension at the club - were also snapped in their new threads.  

The Red Devils will take on their arch nemesis beneath the iconic Wembley arches for the right to deny the Cityzens a chance at a historic Treble - with United the only English side to do so so far.

It will also be the first time ever that the two bitter rivals have faced off in the final of football's oldest competition in its long and illustrious history. 

Players were treated to a fitting earlier in May at their Carrington training facilities in order to be properly sized up for the big occasion. 

Representatives from Paul Smith - the club's official formalwear partner - took their measurements. 

It comes just over a week after a not-so-subtle jibe from legendary United boss Sir Alex Ferguson at the club's other rivals, Liverpool. 

The Reds famously turned up to Wembley in dazzling white suits in 1996, only to end the game with runners-up medals. 

And when Ferguson was invited to give Sale Sharks a pep talk ahead of their Premiership final against Saracens, he could not resist a dig at his old foes. 

'You don't want to lose on Saturday and I wish you all the best,' the Scot said. 'The thing is, I'm telling you, don't wear a white suit for Christ's sake!'

However, while the Reds went with white, United have made the perhaps bold decision to wear blue - the colour of their cross-town nemesis Man City - on perhaps the biggest day of their season.
