Arsenal boss Arsene Wenger is well aware his side faces a mammoth task in attempting to defeat Dinamo Zagreb on Wednesday night.

The Gunners open their Champions League Group F campaign with a trip to the Maksimir Stadium to meet the current Croatian champions who have not been beaten in any form of the game in 41 outings since November 2014.

"Croatian football always produces top level technical quality, that is their strength," said Wenger of the task his side has in front of them.

"We have to focus on our own performance and to beat them have to play at our best and without speculating on any weak link in a team that has not lost a game for 11 months."
