The right-back played the full 90 minutes of last night’s thrilling 3-3 draw at the Vitality Stadium.
He didn’t have his best game in an Arsenal shirt, but the Gunners fought back from three goals down to secure an unlikely point.
And Wenger admits he nearly didn’t start the Spaniard after he picked up a knock in the 2-0 win over Crystal Palace on New Year’s Day.

“He had a knock, he was uncertain to play,” Wenger said.
“That’s the problem when you have only 48 hours, you have to play some players who come out of a game like Crystal Palace [with knocks].
“We had three or four players who we had to wait for the warm up to see if they could play.”
And when discussing who the other players he could have used instead, he added: “We had Koscielny, we had Gabriel that I didn’t start in the end because I was not in a position, and then I did not start Oxlade-Chamberlain because I did not take a gamble with him because I don’t know who we have to take off.
“You cannot take the fresh player out but then you cannot, the players who have played 48 hours before, you cannot take them out.
“It complicates a lot, the job. But we have to shut up and cope with it.”
Arsenal remain fourth in the Premier League table.
