I think that if you take the City example, you can see the effect of Rodri missing.
I wanted us to sell Gana (which Brands did) and the €30mil fee was insane at the time.
He was replaced by Gbamin and Delph.
I am, to this day amazed Brands signed Delph. Although, was it really his signing?
Gbamin may have been a super DM but Silva threw him in when all the vocal 'experts' were saying he was not fully recovered from a previous injury and not match fit by a stretch.
Was Brands at fault or Silva, a bit of both or just bad luck?
Personally at the time I didnt question Gbamins signing but combining both fees and wages I'm sure we could have signed one brilliant DM to replace Gana.
Silva's downfall was the lack of any servicable DM.
