The duo, who have thigh and shoulder injuries respectively, will face late fitness tests ahead of tomorrow's match.
Speaking at his pre-match press conference, the manager said: "Overall we don't have any more injuries than we had before the West Brom game. Flamini has a small shoulder problem. Ramsey we have to check him today.
"I believe that there is nobody really injured from the West Brom game. I don't think [either will miss the match]. I'm quite optimistic about them.
"Ramsey has a little thigh problem but he should be alright. He has a test. He is going back to Wales, certainly, for him it is always special. But you know Aaron Ramsey is a tough boy. He has a test and I think he will get through."
Arsenal currently sit at the top of the Premier League table.
