As an Everton fan I believed at the time and still do when Utd bought him that Lukaku is the best striker in the world.
He may not have the silkiest of first touches but it's not near as bad as people make out.
Everything else he's up there with the best. Heading, clininal, pace, strength, power, attitude, shooting, passing etc
For us it was like having Lineker and Drogba rolled into one player.
I still don't think he would ever suit Barca although he would probably score about 30 or 40 goals a season for you.
Happy for both him, Martinez and Fellaini. I bet Mirallas wishes he had of worked a bit harder over the last few seasons.
