Arsenal boss Mikel Arteta explained his changes for victory over West Ham.
Arteta, surprisingly, dropped Mohamed Elneny and Ainsley Maitland-Niles in favour of Dani Ceballos and Bukayo Sako.
The Gunners chief was quizzed about his decision before kick-off and revealed he drafted in Ceballos and Saka to give his side a different dimension.
"Every game demands different things," he told Sky Sports. "I want to keep everyone involved.
"Last season we won this game but there were so many aspects we didn't control and we were lucky to win. We need to do better tonight."
