one of the summer's most enticing friendlies, who makes our strongest possible combined XI from the two squads? DAVID DE GEA
Now regarded as one of the world’s best goalkeepers, De Gea would edge out Marc-Andre Ter Stegen and Claudio Bravo.DANI ALVES
United tried hard to sign the Brazilian right-back this summer, but he chose to extend his contract at Barcelona instead.GERARD PIQUE
Slipped through the net at United, with Sir Alex Ferguson selling him to Barcelona due to Pique’s frustration at being unable to break up the Rio Ferdinand-Nemanja Vidic defensive partnership. JAVIER MASCHERANO
Still best as a defensive midfielder, but despite his lack of height, the former Liverpool player continues to impress at centre-half for Barca. JORDI ALBA
One of the most attack-minded left-backs in the game, Alba has become a key figure for Barca since arriving from Valencia in 2012. BASTIAN SCHWEINSTEIGER
The United new-boy has won everything with Bayern Munich and Germany, so his experience and winning mentality would secure him a place in a Barca-Man Utd X SERGIO BUSQUETS
One of the best defensive midfielders in the business and a crucial element of Barcelona’s success over the past decade. ANDRES INIESTA
One of the best midfielders in the world, so he would walk into any team. An iconic figure for Barcelona and Spain.NEYMAR
A superstar who scores goals, makes goals and adds colour and flair to whatever he does. LUIS SUAREZ
One of the best attacking players ever to grace the Premier League, but despite his dark side, a footballer who is undoubtedly one of the most prized forwards in the game. LIONEL MESSI
Arguably the greatest footballer ever to play the game. No justification required.
