Comeback kings Watford handed Arsenal a first defeat in eight matches as Marco Silva’s men recovered from a one-goal deficit to snatch a dramatic 2-1 triumph at Vicarage Road on Saturday.
Per Mertesacker marked his first Premier League start in 532 days with the opening goal, the defender converting Granit Xhaka’s corner in the 39th minute, to put Arsene Wenger’s side on course for a fifth successive win in all competitions.
However, Watford – who had scored late goals to pick up points away at Swansea City and West Brom in their last two outings – once again demonstrated their new-found resiliency under manager Silva.
A 71st-minute equaliser from the penalty spot by substitute Troy Deeney got the hosts on level terms and set up a thrilling finish.
After Etienne Capoue hit the post, the game appeared set to finish all-square until Tom Cleverley popped up with an injury-time winner, completing the recovery mission and sending Watford above Arsenal and up to fourth in the table.
