Arsene Wenger says that his free-scoring Arsenal side will only get stronger during the dark days of the English winter. The Gunners manager is convinced they can make a real push for the Premier League title with their own brand of cutting edge football. Wenger was beaming after his side dismantled Wolves 4-1 at Molineux to stretch their unbeaten run in all competitions to 13 games. With each passing match day they are looking more like genuine contenders. Not that Wenger is surprised as he said: "I have had belief since the first day of the season. I hope to keep convincing the players they could have a interesting part to play in the championship. "The most important thing is to play for each other and keep your belief. In this job there is never enough belief. We want to give our best in every game and that is what we are doing." Arsenal are averaging more than three goals a game in the league with 36 goals from just 11 matches. Sunderland are next up on Saturday week and may be entitled to feel slightly nervous. Cesc Fabregas scored his sixth goal of the season yesterday while Andrey Arshavin weighed in with his fourth in the domestic campaign. Robin van Persie leads the way with seven goals while even defenders Thomas Vermaelen and William Gallas have also found the target regularly.
