Arsenal manager Arsene Wenger has warned Chelsea boss Jose Mourinho that Gunners are ready to take revenge from last season's defeat at Stamford Bridge, by securing three points in their visit to West London on Sunday 5 October.

The Blues humiliated Arsenal's defenders in the London derby last campaign with a counterattack masterclass to secure a 6-0 win, coinciding with Wenger's 1,000th match as Arsenal manager.

The French boss admits nobody at Arsenal can forget that heavy defeat and that they are looking forward to payback this Sunday.

"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," the manager said during the press conference ahead of the game.

"Last year's slow start exposed us to counterattacks. It was a very bad memory but football is not made of history, it's performance."

Furthermore, Wenger reveals Nacho Monreal is ready to return to action to eases the injury crisis – with Mikel Arteta, Aaron Ramsey, Olivier Giroud, Theo Walcott, Yaya Sanogo and Mathieu Debuchy still on the side-lines.

"Monreal might be back for us. No major changes elsewhere," he said.

"I've been told Ramsey could be out for three to four weeks, so I count four."

Chelsea are leading the Premier League after an impressive start to the season, securing five victories and just one draw from the first five games.

Following a 1-1 draw against Tottenham in the North London derby last weekend, Arsenal are fourth on the table, six points behind Chelsea.

"We want to go to Chelsea to win. The fact they are six points ahead makes that desire even bigger. We are both still unbeaten but I feel we have had a more difficult run than them. It's a vital game for us to stay in the race," Wenger said.

"The most important thing is to be at the level we want to be on Sunday. Chelsea are very good defensively. Chelsea won the Champions League with good defensive stability. They have one of the best defensive records in England"

Wenger adds the Gunners are also in a confident mood after their excellent Champions League 4-1 victory over Galatasaray on Wednesday night, with new signing Danny Welbeck scoring a hat-trick.

"The win was good for the confidence of the team and we were very efficient.

"You can see that he [Welbeck] is improving. That is very positive and there's a lot more to come from him".

Meanwhile, speaking about Mourinho, he said: "I work for my club and I want them and our fans to be happy after the game. That's nothing to do with individual confrontation"
