Arsene Wenger explains how Arsenal's victory over Manchester United can help Gunners beat Bayern Munich

Arsene Wenger says Arsenal's "vital" victory over Manchester United in the Premier League will help them beat Bayern Munich in the Champions League clash on 21 October. The Gunners sealed a 3-0 victory over their arch rivals at the Emirates and it was their first win over the Red Devils in the league since 2011.

In the Champions League, the north London club are without a win after losing the first two opening games against Dinamo Zagreb and Olympiacos. They face the Bundesliga winners twice in the next two fixtures and defeat to Bayern in both the matches could end Arsenal's hopes of qualifying for the group stages.

Pep Guardiola's side are unbeaten in all competitions this season. Wenger explains how the Gunners can seal victory over "unbeatable" Bayern in order to keep their hopes of progressing to the next round of the European competition alive.

"First of all, we had a very disappointing result three days before against Olympiacos and of course that was a huge shock and secondly it was for us an opportunity to get two points behind the leader, level with Manchester United," Wenger is quoted as saying by the Mirror.

"We also beat them, and on top of that, the third, in recent years we have not beaten United in Championship so on three fronts it was a vital win for us."

"You mean how to beat the unbeatable? First of all, by doing exactly what we have done against Manchester United, playing at a huge pace and by playing with the same belief and by not letting them dictate the game."

"Bayern likes to have the ball, they like to get you back and so we have to win the ball well and be very well-organised and to use our opportunities to go forward with the maximum pace. The United game was significant on two fronts."
