You're just digging yourself a deeper hole, Marca are hardly the outlet you want to visit for a balanced piece. They'll print whatever it takes to paint Madrid in a good light, have you forgotten about the photoshop pic?
As for Lukaku, he scored 25 goals last season in PL while playing for a midtable side. He'd have won the golden boot too had Harry Kane not stat padded vs likes of Leicester and Hull in last week. Rashford comparison is laughable considering he went six months without a league goal last season, again I don't think you've seen enough of Lukaku.
If you are baffled by how players can be worth this much, your club paid 45 million Euros for a 16 year old kid in this window. Irony is smacking you in the face, so stop embarrassing yourself further and take a hike.
Basically this, no amount of whinging can hide the fact that price is absurd for both players. At least with Lukaku he's a proven goal scorer in England.
