London - Arsene Wenger believes Arsenal can overturn their Champions League deficit against Monaco after having watched his side's free-flowing 3-0 victory over West Ham United on Saturday.
The Londoners will again need to be at their attacking best in the French principality on Tuesday after Monaco bullied the their way to a 3-1 win in last month's last-16 first leg tie.
"We have a massive challenge but we will give absolutely everything to try and go through," manager Wenger told Sky Sports television.
