There aren't too many players who literally play well in almost every team and on a constant level, not only a few games on the top level and then you don't even notice for a few weeks whether they are even on the pitch.
I get that people expected him to be a lot better considering his Inter career, but serie A and premier league are very different, and Inter is also very different from Chelsea as well, which is why it was always obvious that Lukaku wouldn't be as good as he was in Inter. I am guessing that when teams are making purchases, they shouldn't just buy players they want, they should focus on getting players that would be better for them specifically.
When he went to Inter Milan and was very brilliant in the attack of the club and he became one of the most in-form strikers in the world then.
I now believe that since Lukaku has played very well in England in the Everton and even Manchester United. He therefore has the experience of playing in English football and would have do well in the second comng to Chelsea but I was wrong. Also Chelsea did not treat him well
