Thomas Tuchel was left 'angry' with his own team selection after Chelsea gave up vital ground in the top-four race following defeat by Arsenal last night.
Emile Smith Rowe's winner, sparked by a misplaced backpass from Jorginho, completed Arsenal's first double over their London rivals since 2004.
Chelsea made seven changes ahead of this weekend's FA Cup final against Leicester and afterwards manager Tuchel regretted his rotation.
'I'm a bit angry that we had so many changes, that's on me. I'm not so happy with the line-up,' he said.
