Arsenal manager Mikel Arteta has taken the blame for his side's exit from this year's Carabao Cup.
The Gunners fell to a 3-1 defeat to West Ham in Wednesday night's fourth round clash and continued their 30-year wait to win the League Cup.
Six changes were made to Arsenal's starting XI by Arteta, with Declan Rice, Bukayo Saka and captain Martin Odegaard on the bench.
"I'm very disappointed. I'm responsible for that," Arteta said.
"We're out of the Cup, we wanted to play a very different game and compete. The game took a direction because of the first goal but we have to see much more from the team and earn the right to win.
"I'm disappointed with myself. We wanted to play in a different way and we weren't able to do that. Every time we lose the pain is there.
"We have to use this pain and this defeat to prepare the best way for Newcastle [in the Premier League] on Saturday."
