We saw the strength and weakness today....strength is he gets on the end of service, weakness is he relies on service (times he had to do stuff on his own he struggled/on one occasion fell over). It's nitpicking yes, but I'm judging him against the very best and he's nowhere near it. Talk of 65 to 70 mill is utter madness, but that's the way the game is going. His own goal tally masks the flaws in his game. Mentioned before, I'd rather have a 15 goal a season forward that makes the attack function really well in every game, than a 25-30 goal forward who adds nothing to the attack as a whole and is invisible against better teams.
Some qualities a top forward needs; A top forward compliments the team and creates for others, a top forward is not anonymous in games when the service isn't on a plate, a top forward has quick movement (especially in the lightning quick modern era), a top forward stretches defenders and pulls them all over the place, a top forward can run the channels and hold the ball up, a top forward has a quality first touch and can interplay with others (quick one twos etc.). Lukaku has none of these things. It's why he is quiet in games against better quality teams when the midfield is pushed back and isnt able to just swing balls into the box on a plate for him. He's too one dimensional to be a top forward. Being an excellent finisher isn't enough. With the exception of Arsenal there is not one team in the top six where he would get in the starting XI. United are short upfront, but his non movement wouldn't compliment Ibrahimovic who needs a mobile player to work off him.
