Arsene Wenger admits Arsenal were not 'mentally ready' to handle Watford after surrendering the chance to gain ground on Premier League leaders Chelsea.
Arsenal crashed to a shock 2-1 defeat at home as Younes Kaboul and Troy Deeney scored inside a dominant first 13 minutes — and the Gunners couldn't come back despite Alex Iwobi's response.
Watford were physically dominant in the first half, creating plenty of chances to further their early lead but Wenger suggested it was Arsenal who were unlucky.
He did concede, though, that the Gunners switched off to lose out in a power surge from Walter Mazzarri's men.
