4) Will Keane
Will Keane’s career at Old Trafford has never really taken off. A knee ligament injury ruled him out of the 2012-13 season, just when it looked like he would force his way into the first team. That was followed by a series of loan moves as United moved on to Robin Van Persie.
United’s shortage of strikers, last season, led to Keane getting a few appearances under Louis Van Gaal. However, his injury woes caught up with him. This resulted in an 18 year old making his debut. That 18 year old was Marcus Rashford and the rest is history.
It looks unlikely that Keane will get in a look in with the first team. At 23 years old, he has certainly outgrown his days in the reserves league. A move seems imminent.
