Arsenal extended their lead at the top of the table to 5 points today, which a 2-0 win over Blackburn in London. Senderos set them on their way quite early, heading home an Eduardo corner in the 7th minute, after some awful marking from Blackburn. Arsenal then dominated the next 20 minutes or so, without scoring, and that allowed Blackburn to come back into it. Rovers couldn't really fashion any chances though, and the Arsenal defence was excellent. Then late on, Alexander Hleb (who had been very good) found space on the right and squared the ball to Adebayor (who had been very shit), and the Togo-stick took either a really brilliant or awful first touch with his left, and thumped the ball home with his right. Game set and match.

Hleb excepted, the best players on show were the defensive ones. Adebayor can't be expected to be amazing in every match, but he was really crap today, although much improved in the second half. Flamini had a very strong game and was really influential. Cesc was craft, if subdued, and Gilberto and Eduardo were erratic but OK. Gilberto doesn't seem like he will be here next season.

The defence though was excellent. Lehmann was calm and solid, Sagna was his usual supercharged, all-action self, and Clichy was solid and alert. Senderos continues to grow in confidence with every game, and his goal was the icing on the cake in this performance. Gallas however was exquisite. Every tackle and interception was excellent, he read the play flawlessly, and made a few drives upfield trying to spur on and support the attack. He was especially important when the team kept conceding possession and gave Blackburn the advantage - he popped up time and time again to win back the ball, and allowed the team to keep its head.

For the first time in a long while, the main Arsenal centreback has the ability to play on either side of central defence. Gallas normally plays on the left when Kolo Toure is in the side, but has been equally adept and impressive on the right side, something which has allowed the defence to stay sharp and settled.

There were previously always problems on this front. Tony Adams preferred the left side of central defence as well, and this worked fine with Steve Bould or Martin Keown complementing him. Adams was accomplished enough to not let playing on the other side be an issue, but his preference was well known. Sol Campbell then arrived, and he too preferred Adams' part of the defence. However, they overlapped for only 1 season, most of which Adams was injured for. Campbell was truly god awful when played on the right-side of central defence, but luckily this was not a problem, as Kolo complemented him perfectly. Senderos too, like Campbell and Adams before him, prefers the left-side, and as a result the Campbell-Senderos partnership was one of the worst seen in recent years.

So after the hiccups and injury problems of 2006/07, the Arsenal central defence finally looks like a top notch unit. Toure and Gallas were hailed as a potential "dream patnership" when the latter signed, and although it took a season to realise that dream, it has happened. Gallas is imperious at the back, and the club finally have a range of good options in central defence. Because of his versatility, Kolo-Senderos, Kolo-Gallas, and Gallas-Senderos are all viable options.

And don't forget about Johan Djourou. He played on the left-side in Arsenal's win at Old Trafford last season, but plays on the right for club and country when paired with Swiss teammate Senderos. His return from injury will be much appreciated methinks.
