#2 Romelu Lukaku, Manchester United

Manchester United's second most expensive signing is warming the bench at the moment. The Belgian international has struggled for form this season and has found the back of the net only four times in his 14 Premier League and UEFA Champions League appearances.
Now, the 25-year-old has lost his starting spot to in-form Antony Martial and Marcus Rashford. Lukaku's last Manchester United start came in October and the former Everton star hasn't scored a goal since mid-September.
Lukaku's poor form has hurt Jose Mourinho & Co. this season. With only 20 points from 12 games, the Red Devils are eighth in the current Premier League standings, with Bournemouth and Watford ahead of them at the moment.
Having paid a huge £75 million for Lukaku, United would want their top striker to get back to his goal-scoring form.
