The Italian giants are spearheaded by Argentinian duo Hernan Crespo and Claudio Lopez, Italian Simone Inzaghi and Yugoslav Dejan Stankovic.
Boss Glenn said: "It will be different from the Celtic game, a little slower build-up but then they have more quality in the last third.
"You've only got to look at their squad. They've got depyth right the way through.
"It will be a test and defensively a real test. That will be interesting for me as manager to see that aspect of our game. We'll have to defend well against them and then see if can cause them problems as well."
Glenn Hoddle is looking forward to the defensive test Lazio will provide his side at the Lane this afternoon.
