If we spent £50m on Townsend, Dembele, Ings (who is out of contract in the summer) and Austin I think I would just give up on football altogether.
We should be looking at teams like Southampton and trying to bring in more quality/cheap players from abroad whilst continuing to bring through some of our youth players. If Lambert had £50m to spend I would hope that he could unearth a few more Okore's and Benteke's and fewer Sylla's, Bennett's, Luna's, Tonev's etc etc.
