5. Giuseppe Rossi
The Italian was only 17 years old when he joined Manchester United. He was expected to achieve big things at United but unfortunately he couldn’t compete well enough with the likes of Cristiano Ronaldo and Wayne Rooney. He only managed to make 12 appearances in his three year spell at United after which he joined Spanish club Villarreal. He scored 82 goals in 192 appearances for them before joining Fiorentina, scoring 19 goals with the Italian club. It would have been great to see what Rossi could have done post the departure of Ronaldo to Madrid.
4. Ryan Shawcross
The English defender came through Manchester United’s youth academy. After making few appearances for the senior side, he was sent out on loan twice. It was becoming difficult for him to compete with the likes of Rio Ferdinand and Nemanja Vidic strongly cementing their place in the first team. This tempted Shawcross to leave and join Stoke City where he has went on to make 395 appearances and become an integral part of the club. One may wonder if things could have turned out differently for him at United had he stayed for a longer duration.
3. Wilfried Zaha
Zaha was signed by Sir Alex Ferguson but post his retirement, the Ivorian failed to establish himself as a regular starter at the club. With United having two different managers in David Moyes and Louis Van Gaal, Zaha never got the chance to rightly prove his abilties. As a result, he joined back Crystal Palace and is now showing exactly what he’s capable of. He is something what United desperately miss these days, a traditional explosive winger.
2. Danny Drinkwater
Drinkwater too was a product of United’s youth academy. Unfortunately, Drinkwater was unable to get a chance to prove his capabilities as he was sent out on loan multiple times during his time at United. Eventually, he joined Leicester City and after going through a lot of struggle and success with the club, Danny finally has a Premier League medal to show off. He has joined Chelsea this summer and has still some of his best years ahead of him.
1. Gerard Pique
The Spaniard is now one of the finest defenders in the world playing for Barcelona. But things would have different had he stayed at United. Alike Shawcross, Pique too struggled to cement his place in United’s starting XI as Vidic and Ferdinand formed a strong and formidable partnership at the back. This only tempted Pique to return to his childhood club and there on, the Spaniard has went on to enjoy a lot of success and it would have been great if United could have a player of his abilities at the club right now.
