Manchester United forward Marcus Rashford turned 20 on Tuesday as an established and key part of the first team at Old Trafford.

Rashford broken into the squad in spectacular fashion under Louis van Gaal, scoring four goals in his first two games against Midtjylland and Arsenal.

He has become a common fixture in the United starting XI, with Rashford now a favourite of Van Gaal’s successor Jose Mourinho, who has used him in all 10 of United’s Premier League games this season having played him 32 times in the league last term.
