The taste of defeat is best savoured in another team's plate than having it served cold far away in Moscow.

Arsene Wenger and his men are in Moscow to keep a date with CSKA after the first leg quarter-final match ended 4-1 in favour of the Gunners at the Emirates.

Wenger has described the unbelievable events at the Stadio Olimpico where Roma taught Barcelona a 3-0 lesson as "good warning" for his men.

"The best way to build on the advantage is to try to win the game, so we will play with our best possible team and have a positive attitude,” said the Arsenal manager, who revealed Granit Xhaka will be absent with flu.

"We are in a position where I don’t think we are under threat of complacency. 

"It is an important target for us to go as far as possible [in the competition]. Tuesday night [in Rome] may be a good warning for us but let us not go overboard as well. 

"Yes, we have a big job to do but we are in a strong position and it is how we approach the game that will be vital."

If the Gunners are to return to the UEFA Champions League, they must win the Europa League trophy like Manchester United did last season.

For all their toils this season, Arsenal arrive in Moscow in good shape. Wenger’s side have emerged from the “negative spiral” Laurent Koscielny talked about before the game in Milan last month.

Four successive defeats left them in a tailspin and their tails between their legs.

There is still no getting away from the fact Arsenal’s season will be defined by what happens in the Europa League. 

Asked whether his own future also depends on success in the competition, Wenger did his best to avoid the question. 

"The Europa League is important for us, everyone knows that," he replied. 

"We are at a stage where we focus on it because in the Premier League we have a very, very, very slim chance to move further up, so the Europa League is one of the big targets now."
