Arsenal manager Arsene Wenger has given one fitness update ahead of the trip to Chelsea; Nacho Monreal may be back in contention.
"Monreal might be back for us there are no major changes elsewhere," said Wenger.
"I've been told he (Ramsey) could be out for three to four weeks, so I count four."
The boss has also revealed that his team have a hunger and a desire to correct the 6-0 defeat from last season, suggesting it was a match he will never forget.
"We will never forget last year at Chelsea and we have an opportunity to put it right. We have a big hunger to put that right."
"Last year's slow start exposed us to counter-attacks. It was a very bad memory but football is not made of history, it's performance."
"We want to go to Chelsea to win. The fact they are six points ahead makes that desire even bigger."
"Our performance will be vital and I believe that it's important to focus and concentrate on our work rate and how we play."
"Chelsea won the Champions League with good defensive stability. They have one of the best defensive records in England."
On the subject of Danny Welbeck, Wenger reiterated statements he made after the striker's hat-trick against Galatasaray.
"You can see that he's improving. That is very positive and there's a lot more to come from him."
The Arsenal boss resisted attempts from the press to draw Wenger into mind games ahead of the game after he was branded a specialist in failure last season by Jose Mourinho.
"He has aways had fantastic teams. It's not a game between two managers, it's a game about clubs."
The boss also talked about Cesc Fabregas, as he faces Arsenal in the Premier League for the first time after leaving them.
"It was his decision. When he left we bought Ozil - we did not need to buy attacking players."
"Everyone respects Cesc here and I want him to get the reception he deserves on Sunday."
"Cesc Fabregas will have a great career because he's a great player. He knows Arsenal had a positive influence on his career."
"I have no animosity against Fabregas. He's a player I love but he made a decision and we have to accept that."
On the subject of Lukas Podolski's future, Wenger reiterated that the German was part of the squad despite rumours of sides attempting to get Arsenal into an agreement over his transfer.
"It is quite simple. There is no transfer market at the moment. We are all on board to get a result on Sunday."
Wenger also praised the mid-week win against Galatasaray in the Champions League, which has given the Gunners momentum ahead of the weekend. He also defended goalkeeper Wojciech Szczesny who was sent off after giving away a penalty.
"The win was good for the confidence of the team and we were very efficient."
"In a fraction of a second you can make the wrong decision. He conceded that it was his fault."
