Jose Mourinho won his first game as Manchester United manager yesterday and then warned his Premier League rivals he has wasted no time in putting his stamp on the club.

Mourinho is determined to hit the ground running next season and claimed he saw clear signs of United playing his brand of football during a 2-0 friendly win against Wigan Athletic at the DW Stadium, his first match since being sacked by Chelsea seven months ago.

Will Keane and Andreas Pereira scored in the second half as Mourinho gave run-outs to 22 players, including new signings Henrikh Mkhitaryan and Eric Bailly, and England left-back Luke Shaw, who made his first appearance since breaking his right leg 10 months ago.

United fly to Shanghai on Tuesday for the start of their pre-season tour of China, where they will face tougher tests against Borussia Dortmund and Manchester City. But Mourinho – who is under pressure to deliver trophies and improve United’s style of play after three troubled seasons under Louis van Gaal and David Moyes – believes the players are adapting quickly to his demands.
