The Germany international centre-back has insisted his side are yet to hit top gear this season and is anticipating a tough test against the Gunners
EXCLUSIVE
Bayern Munich defender Mats Hummels has insisted that his side are not playing their best football at the moment, giving hope to Arsenal ahead of their Champions League tie.
The Gunners face a daunting task against the Bundesliga champions, with the north Londoners having been knocked out at the last 16 stage by the German giants in two of the last four seasons.
Arsene Wenger takes his side to the Allianz Arena for the first leg of the first knockout round on February 15, but Hummels is fully aware that Bayern are not currently firing on all cylinders.
