Arsenal were largely untested during the goalless draw at the London Stadium bar one moment of panic in the closing minutes of the match when a loose pass presented Javier Hernandez with the chance to snatch all three points for his side only to be denied by the crossbar.
The Gunners are now seventh in the Premier League and Wenger said: 'Our performances are not reflected by results. We've not conceded any goals in the last couple of games and we were unlucky against Manchester City, but we have got to take the positives.
"Southampton was similar to tonight".
"It's true, it's a bit frustrating, we had to keep confidence in our game and we go through a patch where there's a difference between what we create and what we score, but that will not last". The patch will not last. Periods like that, adjusting finishing is not right'.
The forward has been struggling for game time under manager Arsene Wenger for some time, but his woes have only worsened since the arrival of worldwide teammate Alexandre Lacazette. "It was hard because they defended very well as well".
'In situations like this you do not focus on one player but the collective attitude of the team.
'I don't want to talk about (the title race).
"That's good to make headlines, but we have to focus on the next game", the Arsenal manager said.
"He is not a sub for me, he is a regular player, but I have plenty of good strikers and you can not play all of them together".
"We don't give up".
As for West Ham, David Moyes's side battled on gamely to record a second successive clean sheet, although the Hammers remain in the bottom three of the table. They're happy to defend, they did that against Chelsea and Manchester City, so we couldn't find the opening and the few chances we had we missed.
'The mood is we're trying to change.
