Am all for solutions but not when the solution could disrupt the flow of things. Yes, Lukaku scores goals but the concerns raised by others here are enough to raise some alarm bells.
Also, is it really a disaster if we don't buy Lukaku this year and then try for Haaland next summer? Yes, our chances to sign Haaland may not be great then but it's still not impossible. And what's the worst that could happen really if we can't get Haaland then? We can either go back for Lukaku, who may be 29 years old then but will likely be cheaper if we want to OR look around the market for any other up-and-coming #9 etc.
