Arsenal defender Laurent Koscielny says they go into their Champions League decider against Napoli full of confidence.
Arsenal lead Group F on 12 points, three ahead of Napoli and Borussia Dortmund and need a draw - or not to lose by three clear goals - to be certain of going through to the knockout stage.
Koscielny, 28, said: "We are on the right track and it's always nice to get ahead start in the Premier League.
"The league season is very long and so is the Champions League, so we need to remain focused.
"We must continue playing our passing football and defending as a unit. It is up to us to maintain this winning mentality."
