Wojciech Szczesny believes that a victory over Marseille tomorrow night will give Arsenal the confidence to keep a winning spirit in the Barclays Premier League as well.
The Gunners came back from a demoralising 2-1 defeat to Tottenham before the international break to beat Sunderland 2-1 at the weekend, and have now climbed to 10th in the table.
And Szczesny says that while the Champions League match will be important for Arsenal’s European standing, it will also give the Gunners the mental strength to keep clocking up wins and moving closer to the top four in England.
“It is a great game for us and if we can get the three points it will give us a massive confidence boost to help us climb the table in the Premier League,” Szczesny told the official Arsenal website.
“It's going to be very important - we realise how big the Champions League is.
“We want to be in this competition and stay in it as long as we can - the Champions League matches are the best. You just love playing in this competition.”
Arsenal face Stoke and Bolton over the next two weeks, and Wenger explained that while many talk about the Gunners losing two big players over the summer, they in fact lost three.
"What people forget is that we lost three key players because we've also lost [Jack] Wilshere,” Wenger said.
“Three who were important in our midfield. Nasri, Fabregas and Wilshere have all been lost and they were the basis of our midfield last season.
"We've had to reconstruct our midfield entirely because Wilshere won't be back until January. Still, we've disappointed this season so far, given what's expected of us, but I think we're on the up again.
“The problem is you can only climb the table slowly. We're not too far away in terms of points from fourth place.''
