Said it in another thread (can’t remember which one) that we could cut Sandro some slack till we’ve seen the players under a different manager…but…a lot of our fans have already made up their minds on Sandro and would rather the players be shit to prove them right
Not sure how anyone can determine his ability, given we don't know his targets (professionally speaking). A Manager is always a bit easier - usually there is some sort of public statement of intent for the club to judge against. Sandro could have been told that team league position is not his concern, just get us some players we can sell for more than we paid. I have no idea how we'd know on that front unless someone went for huge sums.
What we can do is look at what public information exists to have an opinion on whether he foots the bill for that type of role or not (not that our opinions mean jack shit) and we can assess the players he brings in against our own personal opinions of what we would expect for our club.
To be fair, he does not appear to have signed anyone as bad as Curran.
