While Maupay is low hanging fruit, I honestly think Thelwell has been one of the better ones for us in recent history. His player sales have been amazing, prices we haven't fetched for a loooong time.
Last years purchases are a big improvement IMHO. Tarkowski, Gueye, Garner, McNeil, Onana, Maupay for 67 million is good business, especially compared to Sigurdson, Keane, Klaassen, Walcott, Pickford, Tosun for double that. While Beto may be a miss, I think its likely Thelwell was told "We have no money, find someone you don't have to pay for for a year" and didn't have much choice.
