Greenwood's signing was criticized by the mayor of the city of Marseille, however, while speaking at Thinking Football Summit, Longoria said: "The comments of the mayor reinforce what we did, [they did] not have all the information.
"We took the decision internally. OK, there was some opposition, that was objective, but at the same time that gave us power to maybe not investigate, because I am not a judge, but to use all the information to take the best decision, which I think we did.
"In our very first conversation with the coach [Roberto de Zerbi] we mentioned Mason's name.
"The coach knew Mason from the past and it was a very quick conversation at the start between all of us because we believe in the talent of Mason.
"There were a lot of conversations between all of us in the weeks leading up to his move. He is behaving fantastically with us and we are very happy to have him playing in our team."
