Arsenal could move 11 points clear of Manchester United with a win at Old Trafford on Sunday.
But United manager David Moyes and striker Wayne Rooney have questioned the Gunners’ staying power.
Wenger said: “What is most important is that we trust in our quality and show the resilience and the hunger to achieve what we can achieve.”
Arsenal have 25 points from their opening 10 Premier League games this season and are five clear at the top of the table heading into the weekend, while they are also on a run of 14 wins from their last 15 unbeaten away games.
But the Londoners have not won at Old Trafford since 2006 and have been beaten on each of their last five trips to United, including an 8-2 defeat in August 2011.
Earlier this week Rooney suggested it was too early to back the Gunners for the title given their history of fading away in the second half of the season.
It was a theme picked up by Moyes in his pre-match press conference as he warned Arsenal that there is still a long way to go in the title race.
“By the end of the season you play every team twice and that’s when things are decided and sorted out. That’s when we will find out who is the best team,” Moyes said.
Meanwhile, ss Manchester United take on Arsenal on Sunday, the key players are raring to go. Let’s check them out;
Arsenal have had a great start to the season and are top of the league. They’ve always played good football and they’ve tightened up at the back. But United are at home and always have confidence at Old Trafford.
Robin van Persie
He’ll be hugely important on Sunday and will have that extra determination to score. He wants to score in every game, but he’ll want to score even more on Sunday against his old team. Robin knows what Arsenal are all about and that knowledge will be important. It doesn’t matter who scores on Sunday though, the most important thing is winning. Victory would send out a big message to our rivals.
Arsenal’s attacking players have been in great form. Giroud has caught the eye, he’s strong, completely different to what Arsenal normally have up front. He’s a big guy who holds the ball up and he’s scored a few goals this season. Whoever plays at the back for will be kept busy, but United should have the experience to deal with him.
He’s been the talisman this season. He’s knuckled down, concentrated on his football and been absolutely fantastic. He’s looked very sharp and is enjoying his football and, of course, he’s scoring goals. He’ll be a vital player for United on Sunday. In these types of games one expects big players to step up and if he does, that will the Red Devils a huge chance of winning.
