Of course. If he scored 25 goals a season it'd be a great buy, but that would require not just matching last season but significantly bettering it. I saw no evidence that he had many more goals in him than we saw last year.Eto'o and Naismith can certainly score goals, but you needed a striker that will basically guarantee you a minimum of around 15 goals per season. Lukaku in my opinion was actually worth more than 28 mill, look at his age for God's sakes. He should have been at least 35 mill in today's market. He's flexible, can play across all attacking midfield positions as well as a traditional striker role, he can hold up the play and get others involved and he could have a resale value in excess of 40mill in the future if he develops a bit further since he is still so damn young. 28 mill is so cheap.
Actually, I've just seen your username and can only presume you're on a windup
