A kind of agree with you. If you start looking at the prices of players that have been purchased already, anything over £20mil would be day light robbery. Lallana went for £25 million, he's in the same categories as Lukaku, but he has english tax. If we went to Chelsea and they reject a £20mil bid, then I wouldn't see any point in negotiating. As for Origi, that's silly. I doubt you can rate a player on a few World Cup games.
As for Welbeck. I'd have him. International and European experience and still young, his wages will be a roadblock for us though.
