Arsenal boss Arsene Wenger says Carl Jenkinson will be back for the EFL Cup clash with Southampton.
The right-back started four games out of six before the visit of Bournemouth as deputy for the injured Hector Bellerin, but was dropped out of the squad against the Cherries completely as Wenger handed a surprise recall for Mathieu Debuchy.
"Carl Jenkinson will play," the Gunners boss said. "I rested him completely against Bournemouth because he played two big games [against Manchester United and Paris Saint-Germain] and I felt he needed a breather.
"Sometimes, mentally three games in a week demands a lot. Carl's back in tomorrow and we'll put Gabriel in the centre, and then we will see for Saturday.
"You forget that it's a big ask. Carl is very conscientious and it takes him time to play completely with freedom. He needs a run of games to play with freedom, so the fact that he can get another game tomorrow, I think we'll already see a different Carl."
