Maybe a bit of complacency has set in. De Bruyne was arguably the best attacking midfielder in Europe but he's aged quite rapidly and been injury prone. Gundogan was a beast for a season before he left and now he's 34 and looking short on legs. Bernardo is also 30 now and lacks physicality. Foden is out of form, Grealish second choice and they sold Palmer to a rival. Walker now has lost a yard, another 34yo. He's let the squad get old and this league is unforgiving in it's intensity. I actually thought Ake did ok today having not really rated him before now but for sure they really miss the screening midfielder and the leadership he brings. United have them in two weeks and for once I'm fearing a hiding.
