So far:
GK: Onana in, De Gea out, Henderson tbd.
CB: Didn't sell Maguire and Bailly, didn't bring anyone. Lost the Pavard bid.
WB: Telles out.
MF: Mount in, Fred out. Didn't sell McTominay and Van de Beek. Amrabat still an option.
W: Elanga out.
CF: Hojlund in, MG (who was suspended anyway) out. Didn't sell Martial.
On the one hand United improved its squad in key positions, even when the jury is still out on Mount and Hojlund. On the other hand the defense is esentially the same as last season (when it was OK until the injuries came), some of the obviously discarded players like Henderson, Bailly and Van de Beek haven't been moved out, and the triple M is still there despite some good offers.
Ideally Maguire-McTominay-Martial could have been sold and Pavard-Amrabat-Ferguson could have been brought in. Then you'd get:
GK - Onana, someone experienced on loan (my money is on Navas) and someone from the youth squad.
CB- Varane, Martinez, Lindelof, Pavard (who can also play WB).
WB- Shaw (who can also play CB), Wan-Bissaka, Dalot.
MF- Casemiro, Amrabat, Mount, Eriksen, Bruno, Mainoo.
W- Garnacho, Antony, Pellistri, Sancho (who can also play as an AM).
CF- Rashford (who can also play on the wing), Hojlund, Ferguson.
Which would be a pretty robust squad IMO. No big stars but no evident weak spots either.
