The Senegalese frontman is sure to get plenty of boos from the Toon Army.
Marveaux said: “Chelsea are full of very good players, especially their strikers. I spoke to Demba after the Villa game and he’s looking forward to Saturday.
“It’ll be strange playing against him. He says he’s been waiting for this game ever since he signed for Chelsea.
“It’ll be a great moment for him but I don’t want it to be too great for him. He’ll want to score and we’re determined he won’t."
