I can't say Utd business has impressed me tbh.
Yoro is a top talent but even Saliba (who's level he can reach but would be lucky to) was 3 years older when he was ready for the PL. If they want to get back to the top 4 he isn't a signing for the immediate future.
The rest of the signings aren't really that great. No secret that De Ligt & Mazraoui have been openly expendable at Bayern for a while with no takers outside of Utd & Zirkzee doesn't seem all that prolific. De Ligt also apparently earns 15m per year at Bayern. After Varane, Sancho etc. old habits die hard in Manchester.
