#5 Romelu Lukaku - £90 million

Romelu Lukaku's valuation has dramatically increased following his exploits in the World Cup 2018, where he inspired his side to an impressive third-placed finish by notching up 4 goals and engineering an assist.
In consequence, the Belgian just fell short of beating Harry Kane to the much-coveted Golden Boot. Lukaku has largely been known for his intimidating physicality and dribbling ability, which have helped him bulldoze the rearguards of several teams.
The 25-year-old has gone from strength to strength since joining The Red Devils last summer, and also stands a good chance of being awarded the armband in the wake of Michael Carrick's departure from the Old Trafford.
With Lukaku only 25 years old and enjoying the peak of his career, it won't be surprising if his market value crosses the £100 million barrier in the coming months.
