Former Manchester United striker Teddy Sheringham urge Manchester United youngster Marcus Rashford to consider his future at Manchester United after he was left out of the United squad that faced West Ham for the Premier League fixture. Rashford was left on the bench for Manchester United's 0-0 draw away at West Ham on Thursday night. The 20 year-old striker has seen limited playing opportunity since the arrival of Alexis Sanchez from Arsenal in the January transfer window. Sanchez has made 18 appearance since he made his debut in the FA Cup win over Yeovil on January 26, while Rashford has made just four appearance since then. With star striker Romelu Lukaku out injured, the 20-year-old England international started against Brighton last week and was criticised by Jose Mourinho, along with Anthony Martial, following last week's shock 1-0 defeat to Brighton. For Thursday night’s trip to the London Stadium, both Rashford and Martial were dropped to the bench as United could only record a goalless draw at the London Stadium but are expected to play in the final Premier League games of the season at home to Watford. Rashford came in as a late substitute replacing Jesse Lingard in the 70th minute but was unable to influence proceedings as the game ended goalless. The youngster exploded onto the scene as an 18-year-old under Louis van Gaal is reported growing increasingly frustrated with the lack of playing time at Old Trafford and Sheringham who spent four years as a striker at Manchester United winning three Premier League titles believes Rashford needs to leave in order to get more "experience". Sheringham told Sky Sports: "I said at the start of the season about Marcus Rashford that he needs to play games. He needs to learn what he can get away with on a football pitch, what he can do, what he can’t do. You don’t learn that by watching other people play. Related Articles Frank De Boer was right.

All you do is sit and watch and you make mistakes later in life. ‘He needs to learn now, he’s an unbelievable talent for me, and he needs to be playing in a first-team somewhere.’ Despite Sheringham’s concerns over Rashford’s role at United, Mourinho insists the 20-year-old will not be leaving this summer, despite his stinging assessment of his players including Rashford who started in the 1-0 defeat at Brighton last week. Speaking ahead of Thursday’s fixture at West Ham, he said: ‘[Rashford] impresses me. "That’s the reason why he was selected for every match of the season, absolutely every match of the season, and that’s why he played in so many of them. So he doesn’t need to leave to play or to need anything." However, the 20-year-old has made 49 appearances this season and was named in the starting XI in 24 of those games.
