Arsenal are 'frightening' and could have beaten Stoke City 10-0 on Saturday, according to Dinamo Zagreb manager Zoran Mamic ahead of their Champions League clash.

The Gunners boarded a flight to Zagreb on Tuesday afternoon, and are set to begin their European campaign against the Croatian side on Wednesday, but Mamic admits it will be a tough task.

'I have watched Arsenal in many games,' he said in a pre-match press conference. '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.'

Mamic was also keen to pick up some tips from the Premier League, calling upon compatriot Slaven Bilic for some advice ahead of the Group F tie.

Bilic's West Ham are the only team to have inflicted defeat on Arsenal so far this season, and Zagreb will hope to become the second team to do so on Wednesday.

'Yes, I have spoken to Slaven Bilic, he gave me some advice,' Mamic continued.

'This is great reward for me as a coach and for our team. We are aware of the reality and quality of our opponents, but with fanatic fight we can achieve something.'
