Former Arsenal midfielder Alex Song believes his current West Ham side can beat Arsenal on Saturday - by employing the same style that brought Monaco joy at the Emirates Stadium two weeks ago.
The Gunners go into the game having won their last seven Premier League home games on the spin but Song thinks that the way Monaco played in their 3-1 victory in the first leg of the Champions League round of 16 gives the east Londoners hope.
Song told West Ham's official website: "I know this stadium very well and I know when you play with Arsenal it's very hard, but I think Monaco is how you want to play when you play in the Emirates.
"The best thing to do is to try to be together, defend together very well and when you have the opportunity to go on the counter attack, you have to do it very well like Monaco did it.
"If you want to go to Emirates and try to play you will not have any chance to win the game there because this stadium is very hard to play in.
"You have to stay together very compact and not give them any room, then take the opportunity on the counter attack.
"If we do this very well like Monaco did, then we can get a good result there."
After a bright start to the season, Sam Allardyce's side have faded since the turn of the year and currently lie in 10th place after no wins in their last six games and back-to-back home defeats to Crystal Palace and Chelsea.
Song, who played for Arsene Wenger's side for seven years, insists the Irons have the capability of producing a big performance and can trouble the hosts.
The Cameroon international said: "We have shown a lot of things this season as a team, especially when we play against teams at the highest level like Manchester City and Liverpool or Tottenham. We've done very well and we need to continue to improve in this way.
"We can play better and hopefully this game on Saturday will be a very good test for us. It has been a long time since we won a game in the league, so we must try to come back and try to win or get one point there.
"Everything is possible in football and we just need to keep believing and trying hard on the pitch."
Song also insists there is no room for sentiment against his former side and that he is fully focused on helping his team try to gain three points.
"They are one part of my life and, because I went there when I was 17, I always say it is my family," he said.
"I know this is a special game for me, but that is football and I have to take all the emotion out and just try to play my game, to play the best football I can to help the team to win."
Song is on a season-long loan at Upton Park from Barcelona. He joined the Catalan side in a £15 million deal from Arsenal in 2012. But the 27-year-old struggled to hold down a first-team place in the side, with the summer arrival of Ivan Rakitic further hindering his progress.
Hammering down a price
Arsenal themselves have been linked with a move for Song in the summer, alongside Liverpool. West Ham are also keen to try and make the signing permanent. Like the Hammers themselves, Song blossomed at the start of the season but he has struggled for form in recent weeks, putting a potential move on hold.
Meanwhile, The Mail is also reporting that West Ham have been told by Arsenal that they will have to pay £10 million to make Carl Jenkinson's loan move a permanent one.
Allardyce has been impressed with the 23-year-old's performances this season and the club's owners are likely to push to sign the player in the summer.
Jenkinson joined Arsenal from Charlton in 2011 in a £1 million deal. He has made 37 appearances for Arsenal during his time in north London, usually filling in for Bacary Sagna when the Frenchman was unavailable.
Arsene Wenger signed Mathieu Debuchy from Newcastle in the summer, allowing Jenkinson to join up with Allardyce. He is ineligible for Saturday's clash as the loan deal stipulates that he cannot face his parent club.
