Cape Town - Arsenal believe they can become the first team in Champions League history to overturn a two-goal deficit away from home when they play Monaco on Tuesday with a last eight place at stake, manager Arsene Wenger said.
The Londoners were beaten 3-1 at the Emirates and must match the principality side and net at least three times at the Stade Louis II.
Ajax Amsterdam, in 1969, were the last team in the European Cup, excluding qualifiers, to overturn a two-goal margin after losing the first leg at home.
