Steve Wigan
Player Valuation: £35m
That statement takes nothing away from the fact Martinez did make him (who was taking about Lukaku as a top player before he picked him up from Chelsea?) and he still is his mentor at Belgium (I think you'll find he is under his supervision there).
It's easier to combat someone else's point of view if you have facts rather than bile I always think.
I'm no Martinez hater, but the best thing he has done for Lukaku in terms of the Belgian team is to take on Thierry Henry as attacking coach. That's who's 'mentoring Lukaku', and while not as definitive as the help Rom has had from Koeman, Henrys input will be very useful.
