Qwiss Yet investment last summer was practically non-existent.
Off the top of my head we still spent the best part of £100m (gross) and even then we seriously wanted to sign Williams and Sesko but neither came off. None of that suggests a lack of ambition to me. Similarly the suggestions already for this summer is that we'll go back in for both players and have already sealed Zubimendi.
So I really don't agree with the narrative that the Kroenke's have given up investing. As Burnsy suggested, I think the only thing that's happening (if anything) is the club are starting to be more critical of the fees/wages we've been handing out willy nilly (which, I think is fair enough).
