Wojciech Szczesny believes that Arsenal can now win any match they take part in, after the side received a massive confidence boost in defeating Chelsea 5-3 at the weekend.
The Gunners are now seventh in the Barclays Premier League table, and have all but forgotten their poorest start to the season in over 50 years.
And Szczesny insists that with Robin van Persie on fire, and the defence finally starting to click with one another, the club are on a winning streak that could take them all the way to challenging for trophies.
"The spirit within the team is very positive and we are very confident going into every single game," Szczesny told the official Arsenal website.
"We feel like we have what it takes to win every game and I am sure we can keep it going.”
While Szczesny had hoped for a win against Marseille in the Champions League this week, he said that he was still very happy with the teams results in the Champions League so far.
"I would have preferred a 1-0 win,” he admitted. “But if you told me beforehand that we would get four points from the two games against Marseille and not concede I would have taken it. I'm pleased with the result.
"It's always difficult in the Champions League because you have to play against top, top opponents but I am confident we can keep our form going and get the results to qualify for the next stage."
Arsenal face West Brom on Saturday, and then Norwich away the next week, before the side take on Borussia Dortmund at the Emirates in their second last Champions League group stage match.
And with the side currently at the top of the Group F table, should they win their next tie, the Gunners will have qualified.
