The Israeli midfielder has been in fine form as last season's First Division champions have crept up to 12th in the Premiership with a three-match unbeaten run.
They showed plenty of spirit to come from 2-0 down to grab a point at Charlton on Saturday with Glenn in the crowd at the Valley.
He reported: "They picked up a good point at Charlton, where I saw them play.
"They are a good, offensive side, they look to play and Berkovic is a good player for them, he makes them tick.
"They've got Anelka as well and good threat in the last third.
"We know it will be tough but if we can get anywhere close to the performance against Arsenal then we'll put ourselves in a good position to try and get a result."
Glenn Hoddle pinpoints Eyal Berkovic as the player who makes Manchester City tick.
