Arsenal boss Arsene Wenger admits winning the Champions League is a huge ambition.
October 1 will mark the manager's 14th anniversary at the helm and Europe's elite club competition is the one thing Wenger's CV is lacking.
When asked whether he suffers sleepless nights about never winning in Europe, Wenger replied: "Certainly, you always do a little bit.
"It goes through your head like if you have something important to do tomorrow. It goes through your head the day before a game and the day after a game."
