You're not showing healthy caution, you're reacting to every bit of 'news' like it's a fact, using it to confirm your own bias and then chatting bollocks on here. This is why newbies weren't allowed to post in the main forums until they'd shown themselves not to be a massive reactionary cry baby.
We've signed 2 players this summer, neither of whom have worked with EtH and by all accounts were suggestions from the scouts, not the manager. One of them isn't even Dutch for crying out loud!
Antony is probably the only player we've signed based on the manager's suggestion that has been a huge failure, in terms of performances, but mostly the price tag. If INEOS had been in place at the time I really don't think that would have happened. Same with Casemiro, which wasn't the manager's signing as he wanted FdJ, who I think we can all agree is a great player and we'd have loved him at United.
The links to de Ligt and Mazraoui are much more to do with opportunity. We can't spend much money until we sell, Bayern need to sell before they can spend, there might be a deal to be done there where we swap out a couple of unsuitable players (AWB and Maguire/Lindelof) for a couple that are a better fit. Not WC players, but players that improve the squad as a whole.
Hirst's article is deliberately intended to rile up the idiots on this forum. It is purely his opinion and he has written it to get people clicking.
If we do sign Mazraoui, he won't start ahead of Dalot when he's fit and Antony is currently behind Garnacho and probably even Amad now on the RW. If Sancho is still here come the end of the transfer window, Antony will probably barely touch a ball until being loaned out in January.
