Arsenal manager Arsene Wenger conceded his side were dominated by Championship side Nottingham Forest in their 4-2 FA Cup defeat on Sunday.
Forest dealt Wenger his first third-round elimination, with Eric Lichaj scoring twice before penalties from Ben Brereton and Kieran Dowell.
No comeback from Arsenal
Per Mertesacker had levelled matters at 1-1 and Danny Welbeck's 79th-minute effort to make it 3-2 failed to spark a comeback from the defending champions.
"I believe that overall we played against a Nottingham team who were very sharp, more dangerous than us and dominated us at the front," Wenger told BT Sport. "After that it became a difficult game.
"I think we were a bit unlucky as well but overall they were sharper than us, more incisive and more dominant in the challenges. We lost too many challenges to win a game like that."
