Arsenal Wenger said his inconsistent Arsenal side are "slowly getting there" following their 1-0 win over Marseille in the Champions League.
Aaron Ramsey's strike in the second minute of stoppage time was enough to move Arsenal to the top of Group F.
"We've taken a little step forward," said Wenger, whose side currently lie 10th in the Premier League.
"We're a team that has to continue to grow and have lost only once in six matches. We are slowly getting there."
The match appeared to be set for a goalless draw after Robin van Persie, twice, and Theo Walcott had been thwarted by the Marseille defence.
But with seconds remaining Wales international Ramsey controlled Johan Djourou's cross before firing in low from inside the area.
"For the qualification it's a very important goal, for the confidence as well," the French manager added.
"Marseille defended in a very disciplined way, but you could see in the last 15 minutes we started to create opportunities. We showed patience and discipline.
The English side were often guilty of losing possession too easily, but Marseille, who went into the match as group leaders, created very little in attack when they had the ball.
"Everyone questioned how we would cope defensively tonight and I think we did well," added Wenger.
Arsenal, already without defenders Thomas Vermaelen, Abou Diaby and Bacary Sagna, suffered another blow when full-back Carl Jenkinson limped off in the second half.
"He had a very good game," said the Gunners boss. "He had a little knee problem so we hope it's not serious. He overstretched his knee."
