Arsenal face the first true test of their title mettle against Manchester City this weekend.
The Gunners sit five points clear at the top the league, and have played a scintillating brand of football this season. Mesut Ozil, Aaron Ramsey and Olivier Giroud have lit up north London and the side will travel to the Etihad Stadium knowing a win would see them instilled as title favourites.
They lost to Napoli in the Champions League in midweek but, thanks to work done beforehand, still managed to qualify for the knockout stages.
There can be no repeat performance on Saturday. Arsene Wenger knows that. So do the players.
City have been invincible at home so far this term. Free-scoring and at times just downright scary, they have been in stunning form.
They have played seven games in familiar surroundings, winning seven, scoring 29 goals and conceding just two.
They have thrashed Manchester United 4-1, Tottenham 6-0 and Norwich 7-0. The Etihad is a fortress.
Arsenal must breach it.
That is what title winning teams do. They travel into the lion’s den and emerge victorious. United used to do it. They have slipped since then, but the point stands. The great Arsenal side including the likes of Patrick Vieira and Thierry Henry did it too.
If they are to be considered the best, this Gunners side must emulate the history boys of previous years.
They have the talent. Not since the days of the ‘Invincibles’ have they boasted such a squad. Ozil is world-class, Giroud has become prolific, Ramsey is riding the crest of a seemingly never-ending wave, Laurent Koscielny and Per Mertesacker have formed a fearsome central defensive partnership and Wojciech Szczesny is now one of the finest goalkeepers in England.
Yes City have talent. But they have weaknesses. Manuel Pellegrini is yet to settle on his first-choice stopper and the defence in front of either Joe Hart or Costel Pantilimon has looked suspect throughout 2013/14.
If anyone can take advantage of that leaky backline it is Arsenal, with their quite brilliant playmaking triumvirate of Ozil, Ramsey and Santi Cazorla.
Should they win, they will finally be seen as the title contenders they deserve to be seen as and will go from strength to strength.
A defeat, on the other hand, would do nothing to destabilise them but the doubts may start creeping back in.
Is this really a team capable of winning the Premier League? We will find out this weekend.
