Manchester United will look to mark their return to Europe’s premier competition with a win over the Swiss champions at Old Trafford, in what is only the fifth meeting between the sides.
Jose Mourinho has already confirmed that David de Gea will start in goal on Tuesday, while Victor Lindelof and Chris Smalling will also come into the team in the heart of defence, and all three players were pictured in good spirits today.
Meanwhile, Luke Shaw, Ashley Young and Marcos Rojo were all involved in the training session too, as they continue to step up their respective comebacks from injury. Marouane Fellaini also took part after missing the 2-2 draw at Stoke City.
