Arsenal manager Arsene Wenger has challenged his side to improve on Jack Wilshere's wonder goal as they look to close in on qualification for the Champions League knockout stages with victory over Borussia Dortmund.
The Gunners moved clear at the top of the Barclays Premier League with a 4-1 victory over Norwich at the Emirates Stadium, where Wilshere finished off a sublime passing move around the edge of the penalty area to set the home side on their way.
It was an 11th win in all competitions for Wenger's men since they lost on the opening day of the season to Aston Villa and has led to talk of a sustained challenge for honours.
Wenger maintains consistent performances at such a high level will hold the key to realising those ambitions.
``We have room for improvement and being in the position we are in at the moment and knowing we have room for improvement is of course a good feeling,'' the Arsenal manager said.
``The 'feelgood factor' is down to the quality of the spirit of the team, the solidarity of the players, and their desire to do well.
``We know we are a team that looks like being successful - for that you need a special hunger and I believe these players have a special hunger.''
Wenger continued: ``I believe in life you can always improve and that is what makes a top-level sportsman or a top-level team, is they always have that surge for improvement.
``I believe that collectively in the way we win the ball back and the use of the ball offensively, we have room for improvement, for more consistency in that and that is what you want from the players.''
Arsenal will tackle last season's European runners-up in a double-header on match days three and four which could well shape the outcome of Group F.
The Gunners are currently top by three points following back-to-back wins over Marseille and, most impressively, Napoli.
``It is not a decider, but it is an important one,'' said Wenger.
``It is an 80 per cent game for me, for the qualifier.
``If we win the game and we win the other home game, we know we are there.''
Much of the credit for Arsenal's impressive run has gone to deadline day signing Mesut Ozil, and Dortmund boss Jurgen Klopp believes the £43million signing from Real Madrid was the missing piece for Wenger.
``This team missed one player and maybe it can be Mesut Ozil,'' said Klopp, who will serve a touchline ban on Tuesday.
``He is technically perfect, he is fast and has developed a drive to goal.
``He is very intelligent, can play in any team. He has everything, is natural and it works very well.
``That is why it was a great idea from Arsenal and not so from the one (team) who let him go.''
Although he recognises his side are second favourites in a match which could go a long way to deciding their fate, Klopp is eagerly anticipating the clash.
``They have more points (than us), are in first place in one of the strongest leagues in the world and they play at home, so will be favourites,'' he said.
``We will have to make one of our best games ever because there is no other chance to be successful here.
``But I think these will be two close games and some of the small things will decide what will happen.
``We have to be prepared for these details and we will see, but, if I had to pay for a ticket, then I think I would pick this one.''
He will be able to watch from the stands all the same, having been handed a touchline ban by UEFA for angrily confronting the fourth official in his side's 2-1 defeat to Napoli.
However, the German has full confidence in his number two, Zeljko Buvac.
``I am full of trust for him, and a little bit less emotion is not always worse,'' he said.
