His exact statement was he knows he can't join a City or top 5 type team mate, that to me shows a player who knows his limitations - so yeah we need more of that type, players who are happy and see being at a 7th place team as the maximum of their abilities.
Unless we are a stepping stone, be boss if he joined and in january he came out with he wants to go to play for Spurs - reckon the fans would be on his side massively in that case
He was decent at Atalanta but not good enough that no one besides boro came in for him mate, typically the better players would have had more interest from other Italian teams (see Kessie now for example at the same team)
