Very good striker who has improved his game a lot in last season. Gets so much undeserved criticism because as a team we don't create enough chances. He is a level below strikers like Kane, Aguero.
And that's the point. I don't think anyone disagree about him being a good striker. We are just aspiring for a higher outcome that's it.
Not sure also it's the problem of our team only. Lukaku had exactly the same doubts hanging over him when he was at Everton and that was one of the main points some were always doubtful about signing him. He's also the same for Belgium, scoring a lot in small games but seems to be always far from scoring in big games even when he is playing well, he doesn't look like he actually get chances in these matches. He played very well against Brazil but at the end his 4 goals came against Tunisia and Panama.
He needs to improve his presence as goal scorer in these kind of games, otherwise doubts and criticism will always be hanging around him. He's not a 30-40m striker to escape it. He can't be a support striker for ever.
He comes out as a nice and very likable lad with great character and I personally love him as a personality, but at this point I can't disagree with anyone who thinks he will have to be upgraded on in the future if a better name becomes available. I'm fine with him leading the line now till someone else appears.
