Arsenal boss Mikel Arteta insists they never considered losing Gabriel Magalhaes over the summer.
The Brazil defender is back to his best and was outstanding in victory over Brighton.
Asked if Gabriel is underrated, Arteta said: "Hopefully not. Certainly not in the team and certainly not from me. I know his value and what he brings to the team. The love he has for defending, to keep a clean sheet and be on it in every single action.
"What he transmits to the backline is absolutely incredible. Today we did against a team that I think has scored in 32 consecutive games in the Premier League. So, big compliment to the boys."
On doubts about Gabriel over the summer, he added: "From my side there was zero uncertainty, because I want him here."
