Rosicky more than deserves his new contract
The Czech playmaker has been one of the best midfielders for the Gunners this year, having come back into the team after injuries and the signing of Mesut Ozil seemed to indicate he'd be heading out of the club once his contract was up in the summer. But those performances have convinced Arsene Wenger to offer him a new deal, and he could do little more to repay his manager than scoring a truly phenomenal half volley at White Hart Lane to win the game.
Arsenal lived dangerously at times
Scoring the goal so early left Arsenal quite unsure of how to approach the rest of the match, and it led to the side sitting back and asking Tottenham to come on and prove they could score against them. As it turned out, they couldn't, but with Arsenal having 41% possession, their lowest of the season, while also conceding several decent chances, it was a risky business, and they had to rely on their outstanding central defensive partnership just a little too much.
Giroud was a non-existant frontman
Arsene Wenger will be disappointed that his frontman Olivier Giroud was so incapable of holding the ball up against Spurs. He would have been relying on the French striker buying the defence and midfield a little respite as Tottenham continued to put them under pressure. His absence for much of the game would surely convince the Arsenal manager to invest in a new striker in the summer.
Koscielny, and the Arsenal defence were immense
Laurent Koscielny and Per Mertesacker have arguably been the best defensive partnership in the Premier League this season, and against Spurs they were pretty much faultless, against a very determined striker in Emmanuel Adebayor. It was particularly a great battle between the Frenchman and Adebayor, with it very much being a to-and-fro for much of the game. One goal line stop by Koscielny to deny Nacer Chadli was one of the highlights of another truly outstanding defensive display.
The three points are all that matters
Despite the close game, and the questionable performance on the whole, Arsenal's first win at White Hart Lane since 2007 brought three points to their continued title challenge, which is after all the only thing that matters. This was undoubtedly the sort of game Arsenal would have lost over those last few seasons, so the fact they came through it with the victory says a lot about how far they've come this year.
