Standard Liege coach Laszlo Boloni has always been full of admiration for Arsene Wenger's football vision - but feels his current young Arsenal side may just be missing something in their quest for European glory.
Boloni - whose side raced into an early 2-0 lead inside the first five minutes of their opening Group H game against the Gunners in Belgium, before losing 3-2 - maintains while Arsenal are certainly are among the European heavyweights, they remain just short of complete dominance.
"I feel the policy of Arsenal is something really incredible and admiral," said the Romanian, who takes his side to the Emirates Stadium on Tuesday.
"Arsene Wenger's policy and they way he manages is very intelligent, and the way he manages his game is also very intelligent.
"I remember talking with him when I was a young trainer, I really admired his intelligence and also his vision about the future of the club - but in comparison to Real Madrid, Barcelona or Chelsea, maybe they lack something."
Boloni, though, is not expecting anything other than another severe test for his Champions League newcomers, with defeat on Tuesday all but ending chances of qualification for the knockout stages.
"Arsenal have some warriors in their team, they are not young lambs," he said.
"It is easy to say 'to go to war', but without the ball it is very difficult. We must have strength to do more than that.
"We will be organised and with our strength we will try to do the maximum so that they will respect us."
Boloni added: "It is always great to come to England and to come to come to such a stadium - it is really a football temple. It would be good to be happy when we leave the stadium as well."
