It's pretty common knowledge now surely - RDZ wanted to sign established players with limited resale value to have a proper go and in turn boost his cred, we wanted to stick to our mix of youth and experienced heads that got us to this point. It's not really a puzzler.
But, interestingly a week after De Zerbi arrived in Marseille and they send a formal bid to 21 year old, Equi Fernández - who we seem to have been tracking for a while. I assume he didn't think the recruitment was all bad!
