With Arsenal taking just two wins from their opening six Premier League games, Gunners fans were become slightly twitchy over their chances of earning more silverware this term. Yet Wednesday's 4-1 win over Galatasaray in the Champions League has renewed confidence around North London.
Danny Welbeck's hat-trick against the Turkish side has given Arsenal supporters belief that the club finally have the goalscorer they needed in order to challenge for trophies, and they face their biggest test of the season so far on Sunday as they travel across London to face Chelsea.
Arsenal famously capitulated at Stamford Bridge last season, falling to a shocking 6-0 loss against Jose Mourinho's side as 'The Special One' once again had the upper hand over his enemy Arsene Wenger. Whilst Chelsea were by far the better side on the day, there can be no doubting that one bizarre incident in the game made sure of a win for the Blues.
Samuel Eto'o and Andre Schurrle bagged two goals in the first seven minutes, before Alex Oxlade-Chamberlain handled Eden Hazard's shot on the goal line, but referee Andre Marriner mistakenly sent off left back Kieran Gibbs instead in one of the strangest incidents of the Premier League season.
Arsenal now return to the scene of that nightmare on Sunday, and Oxlade-Chamberlain believes his team can get revenge for that defeat.
"It was a horrendous day. You would like to say it was one that you forget and don’t remember, but I’m sure it’s one that I’m going to remember for the rest of my life," said the England international.
"They are big competition to us so we’ll be looking to go there and make a statement early on in the season. I definitely believe we can," he added.
Chelsea have so far been the team of the season with five wins and a draw from their opening six games of the season, and whilst Arsenal will have renewed confidence of beating the Blues with an in-form Welbeck, keeping Diego Costa quiet will be the key to their chances of claiming three points.
