At the age of 24, Romelu Lukaku has already played for four Premier League clubs and become the division's most expensive striker.
Chelsea snapped up the Belgium striker from Anderlecht, but a season later he was loaned out to West Brom without having scored a single goal.
Lukaku scored an impressive 17 goals for the Baggies before returning back to Stamford Bridge.
The striker failed to score in three games for Chelsea the following season before again being loaned out, this time to Everton.
