Arsene Wenger said Arsenal looked incapable of scoring as they slumped to an EFL Cup quarter-final elimination at the hands of Southampton.
Goals from Jordy Clasie and Ryan Bertrand secured a 2-0 win for the Saints and a first League Cup semi-final in 30 years at Emirates Stadium on Wednesday.
Wenger made 10 changes from the weekend's 3-1 win over Bournemouth and was rewarded with the Gunners' first defeat since the opening day of the Premier League season.
"It was one of those nights where it looked like we can play for two hours and not score a goal," the Frenchman said.
