Per Mertesacker: We’ve lost our killer instinct

Per Mertesacker insists Arsenal’s season is not over — but has called on the club’s goalscorers to rediscover their killer instinct.

The Gunners were knocked out of the FA Cup on Sunday afternoon as Watford secured a 2-1 win at the Emirates Stadium to eliminate the holders and book their own place in a Wembley semi-final.

Odion Ighalo ended a personal barren spell in front of goal by putting the Hornets ahead before Adlene Guedioura lashed in a second to send the 12-time winners out — despite Danny Welbeck’s late strike setting up a grandstand finish.
