I do not agree with this statement,
Yes he dropped Werner but we do not want to compare a Werner with a player like Lukaku ( Market Value over 100 million! )
As we only take a look at his statistics ( 250+ goals where Werner not even come at half this amount! ) and then I do not mention the difference between work ethics, physical strenght, speed, agility, ball control, ...
40+ goals for Anderlecht ( some of them even when he was under 18 years! ), then he succeeded in the premier league for West Brom, Everton ( nearly 100 goals! ) and Man U. He made those goals against some of the best defenders at the moment of the world. They just stood there like they were helpless children.
He made Inter Champion and competed there for top Scorer with Ronaldo.
He is a potential candidate for Fifa ballon d'Or. He just need some more time, confidence and of course the ball. He cannot do everything by himself. Even with limited ball touches he gave nearly single handed the World cup for Clubs to Chelsea this year.
I do not care about the number of ball touches ( with the red devils it is often also very limited ) but if there were statistics of the quality of ball touches, he would be top 3! Give the ball to Lukaku and watch magic happens.
