Graham told BBC Five Live: "I think Arsenal will beat Chelsea, although if there's one team that can keep a clean sheet at Highbury it's Chelsea - I'm very impressed with them defensively.
"They're churning out the 1-0 victories, but Arsenal can get so many goals from different parts of the pitch.
"One problem could be that some of Arsenal's form boys are not used to playing this number of games.
"Sometimes a little setback like yesterday could suddenly make the tiredness element come into play. Wenger must eliminate that as soon as possible. But I'm still backing Arsenal to get through on Tuesday."
