#4 Romelu Lukaku
The 25-year-old was the subject of a bidding war in the summer of 2017 between Chelsea and Manchester United, with the Red Devils eventually winning the race.
That deal made him the most expensive striker of all time in the history of the Premier League and he performed creditably well in his debut season at Old Trafford, scoring 27 goals in all competitions as United finished in second place in the Premier League but trophyless.
It has gotten worse for Romelu Lukaku this season, as he has struggled for form in front of goal. This season, Lukaku has scored just six goals in 22 matches across all competitions and these are poor numbers for a top striker.
Goals win matches and if United are to turn the tide in their woeful campaign till this point, then Belgium's record goalscorer must start to do what he was bought for - which is to put the ball in the back of the opposition net.
