#3 Luke Shaw
Luke Shaw is the epitome of a promising talent whose career has been (arguably) damaged beyond repair, following a spate of long-term injuries alongside flagrant lack of concern for his fitness. His weight seems to fluctuate each season, with his latest physique appearing "bulky" to some, but overweight to most spectators.
Shaw made 11 appearances in the Premier League for United last season, most of which were late substitutions. He can still turn his career around with a move to a mid-table Premier League side who would offer him lots more game time than he currently gets, but it's more likely that Shaw will stay at Old Trafford and try to work his way back into the team.
Where might Luke Shaw go?
Everton were linked most recently with the left-back, but Shaw had reportedly turned down the offer in favour of proving Mourinho wrong this season. Spurs were also rumoured to be interested, however no bid has materialised thus far.
