Bayern Munich manager Pep Guardiola has said his team's two goal lead over Arsenal in the Champions League is potentially 'dangerous'.
Bayern won 2-0 at the Emirates with goals from Toni Kroos and Thomas Muller after Arsenal goalkeeper Wojciech Szczesny was sent off. But the ex-Barcelona boss says the tie is not over yet.
"Winning 2-0 in London was a very good result for us, but it is also dangerous," said Guardiola.
"We have a very good chance to go through, but we have to be in the situation that we really focus on the game.
"We have to do our best."
Arsenal have experience of winning at the Allianz Arena as they beat the German champions 2-0 in the same fixture last season and were only knocked out on away goals.
The German side are currently well ahead at the top of the Bundesliga and Guardiola has insisted that his team will not rest on their laurels against Arsenal in the second leg.
"The Champions League is a huge game for us, it is not like a day-to-day game in the Bundesliga."
"We have to bring our ideas across in the way we play, and know what the strengths are."
The Bayern coach stated that the key to success against Arsenal is to play the possession game and don't let them play with freedom.
"They have a lot of quality, so we have to make sure we have a lot of possession."
Bayern Munich host Arsenal at the Allianz Arena on Tuesday in the second leg of the Champions League last 16.
