Per Mertesacker insists Arsenal’s season is not over but he 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.
The result means Arsenal cannot become the third team to win three successive FA Cup trophies and has seriously dented their chances of silverware of any kind this season.
They now go to Barcelona on Wednesday night looking to overturn a 2-0 home defeat from the first leg of their round-of-16 clash with the reigning Champions League holders, and a team at the top of their game.
After that a tricky trip to Everton in the Premier League could see Wenger’s men more looking over their shoulders rather than up at pace-setters Leicester following a dismal run of two wins in nine league games.
Wenger has been constantly defending both his position as manager and Arsenal’s chances for success this season, labelling speculation over his own future as “boring” and “a farce” on separate occasions.
And Mertesacker has backed up his manager’s claims – insisting there is still something to fight for despite the latest setback.
“It is as you can imagine, we are out of the competition and the treble dream is over, that is (the) conclusion of today’s game,” he said when asked about his disappointment after the game.
“The season is not over. We play in a confident way, we maybe lack that bit at the end.
“What is really important in football, to be successful we need to score. The desire to play together and to be good at a team is there, you can feel that, even if there is a bit of negativity I can understand.”
Mertesacker was involved in both of Watford’s goals and he failed to clear Nathan Ake’s throw-in which Troy Deeney knocked into Ighalo’s path before turning his back on Guedioura’s rocket.
But the German World Cup winner believes it is at the other end of the pitch where Arsenal’s problems lie.
“What we do lack at the moment is we need to score at some point,” he added.
“It looks like we play, and play and play until the opposing team scores. That is something we need to work on. We had the opportunities and the possibilities when they were 2-0 up to come back and we kept going.
“You have to give credit because we kept going and created chance after chance, but at the moment we lack that killer instinct.
“We need to work on that if we want to be successful in the Premier League and the Champions League.”
