Dinamo Zagreb coach Zoran Mamic has admitted that Arsenal will provide formidable opposition for his side when they meet in the Champions League this week.

Arsene Wenger's Gunners will travel to Croatia to begin their Group F campaign on Wednesday evening.

Mamic has said that he has been impressed with what he has seen from the North Londoners so far this season.

"I have watched Arsenal in many games," he told Goal.com.

"I went to see them against Stoke this weekend and I got the impression they were playing in second or third gear, and should have won 10-0! It is frightening and fascinating how they play. I believe we will be better than Stoke.

"Cazorla and Ozil are key Arsenal players, but the team is so strong that danger comes from everywhere."

Zagreb are looking for their first win in the Champions League since 1999.
