Paul Pogba and Alexis Sanchez both played in Manchester United's behind-closed-doors win over Blackburn Rovers U23s on Sunday.

According to the Daily Mail, Sanchez payed 65 minutes and was joined by a number of first-team players in the match.
Sergio Romero, Matteo Darmian, Axel Tuanzebe, Jesse Lingard, Mason Greenwood and Tahiti Chong also figured in the resounding 4-0 victory.
Lingard grabbed a brace, while Chong and Greenwood also scored.
