After the Gunners' second successive 0-0 draw against Stoke, the manager complimented his opponents' defences and commented that his side's new signings in attack need time to gel
The Gunners are the only side in the Premier League yet to score after playing two games, recording two 0-0 draws as they open the season without the departed Robin van Persie.
Wenger, however, is not worried telling the club’s official website: "It is never disastrous to take a point at Stoke but we lack a little bit of oil in our engine in the final third.
"I still feel on one hand it is two points dropped but overall we know at the end of the season that Stoke is a difficult team to play against. They can always win games here and today they were highly committed."
The north London club were allowed few chances in either of their opening matches, and Wenger went on to praise his opponents’ defensive organisation.
"I put it down to having new strikers and as well because we have played defensive teams who are very well organised - Sunderland and now Stoke," he added.
"If you look last year at the teams who allowed the least possession behind their midfield it was Sunderland and Stoke.

"We played them in the first two games and I have seen much more open games. I don't deny anyway that we should have scored and that's what we need to work on."
New signings Santi Cazorla, Lukas Podolski and Olivier Giroud all started on Sunday, and Wenger believes his side’s attack will improve with time.
"What looks completely natural when we are at our best still is not there, and we have to work on that, by practising on how we want to move, on the quality of the final pass," he commented.
"Today we had Giroud, Podolski and Cazorla together up front - one month ago they didn't know each other. It is the department where we have the most new players."
