Marcus Rashford and Jesse Lingard have enjoyed meteoric rises at Manchester United over the past few years.From academy prospects to guaranteed starters, the English duo are recognised as the future at the Theatre of Dreams.Rashford, 21, made his Premier League debut for United just over three years ago during a 3-2 victory over Arsenal. He scored twice that day.Since then he's bagged a further 25 league goals, displaced Romelu Lukaku as No.1 striker and become an England regular.Six goals in 31 appearances for your country - including at the 2018 World Cup - at just 21 years old is pretty remarkable.As for Lingard, the 26-year-old has earned a reputation for scoring important goals for United since making his senior debut in 2014.He scored the winner in the 2016 FA Cup final against Crystal Palace and then United's second in the 2017 EFL Cup final, where they beat Southampton 3-2.Four goals in 22 appearances for England is also a decent return from the winger.Both Rashford and Lingard are living proof that young and aspiring English players can make the grade if they're good enough and work hard enough.They've become role models at United, though you wouldn't have guessed it from their behaviour during the Under-18s' game against Sunderland U18s on Saturday.Funny footage has emerged of Lingard throwing a ball at Rashford as he watches the match and then Rashford chasing after him like school kids.Meanwhile, United U18s were losing 1-0 and trying to find a way back into the game. Check it out below.

Expect nothing less from those two.

United U18s ended up recovering to draw 3-3 but with no thanks to Lingard and Rashford, who were too busy messing around with each other to watch.
