Tomas Rosicky has warned the rest of Europe there is more to come from both him and Arsenal this season.
Now fit again following a string of injury setbacks, the Czech winger made his first start since January 2008 in last night's Champions League Group H opener away to Standard Liege, where the Gunners fought back from going 2-0 down inside five minutes to win with a late strike from Eduardo.
While there may have been a touch of good fortune about Thomas Vermaelen's scrappy second-half equaliser, when Alex Song looked offside and used a hand as he knocked the ball back into the six-yard box, Rosicky believes the manner of the turnaround will have sent a message this young Arsenal side are in it for the long-haul.
"You have to believe in the style we are playing, we did that,'' said Rosicky, who came on as a substitute during the Premier League defeat at Manchester City last weekend.
"It is really satisfying when you can turn a match around like this.
"If you do not believe, you cannot turn a game like this.
"You just have to continue to pass the ball like we always do.
"We know that inside we are strong enough to turn games like this, and that is what we proved in Liege.''
Rosicky added: "We knew that after the two defeats in Manchester, we needed a result.
"The performance in Liege will help with the confidence.''
Czech midfielder Rosicky has endured a frustrating 18 months on the sidelines, progress hampered by complications to his initial hamstring problem and then suffering another slight strain after he returned to action in pre-season.
However, Rosicky, a £8 million signing from Borussia Dortmund in May 2006, is now ready to make an impact.
"I am not anywhere near my best, and still have plenty of room to improve. I will get better,'' he said.
"I am fired up to win a trophy and enjoying being back. It is good that I can be part of this team back again.
"The boss has another option with me in the creative part of the game and he still has [Samir] Nasri to come back.
"Offensively we are very strong and I can help with that.''
Rosicky, though, admits it was a tough rehabilitation.
"Of course it is difficult when you are out for such a long time, but when you play, you just have to try to forget that,'' he said.
"I am just enjoying being back, I am fit and am itching to play football again, but I have to take things step by step.''
Arsenal captain Cesc Fabregas, meanwhile, feels he paid the price for being too honest after being caught in the face by Eliaquim Mangala as the defender lined up to shoot Standard's opening goal.
"Maybe I am very small and they are very big, but they always catch me on the face,'' the Spain midfielder said.
"But if you go down, they say that you cheat so you try to be nice and stay on your feet.
"However, after you get caught they score a goal. I guess sometimes this happens in football.''
Gunners boss Arsene Wenger feels last night's victory will have "strengthened the belief'' within the Arsenal camp following what has been a difficult few weeks, in the wake of successive domestic defeats and Eduardo's European ban for diving which was overturned on appeal.
There is little respite for the Gunners, though, as Wigan visit Emirates Stadium on Saturday before another home game against West Brom in the Carling Cup, when 18-year-old forward Sanchez Watt, on the bench in Liege, looks set to feature in a youthful Arsenal XI.
Fabregas said: "Now let us focus on Wigan because the Premier League is the most important thing for Arsenal.
"When we play every three days, it is always like a final for Arsenal who want to be at the top.
