Philipp Lahm: 'We'll guard against complacency'

Bayern Munich captain Philipp Lahm has insisted that the team will not become complacent following a 2-0 victory over Arsenal in the first leg of their Champions League last-16 tie.

Pep Guardiola's side scored two crucial away goals at the Emirates Stadium, but Lahm believes that Arsenal can respond in the same way that they did last season when the Gunners were knocked out by Bayern despite winning at the Allianz Arena.

"It is a good result to take back, but we have been warned by the match last year," the German defender told reporters.

"All of us who were there know how quickly things can go wrong. We need to be alert from the first minute once again."

The second leg of the tie takes place on March 11.
