Ten and counting. Ten occasions on which Arsene Wenger and Jose Mourinho have met as managers; ten occasions on which Wenger has failed to win.
The architect of his frustration stood imperious on the outer reaches of the technical area throughout this, the latest rain-blasted edition of their rivalry.
It was Mourinho’s night, in more ways than one. He will have felt most pleased with the result, his team turned in the better performance, and the inhospitable conditions reflected his gameplan.
Getting heated: Arsenal and Chelsea players come together during an ill tempered game at the Emirates
Chelsea were not negative, but they were constant, cussed, spoiling, much like the rain that drenched the Emirates Stadium and many within. Chelsea’s organisation won the day, as did the weather.
It was a night on which it was impossible to play the beautiful game, and Chelsea settle more happily into the ugly side of things.
They resisted Arsenal defiantly, broke more threateningly on the counter attack. Arsenal were limp and ineffectual for long periods. Wenger had sought a reaction to the 6-3 defeat at Manchester City, but this wasn’t it.
A defeat would have been worse, but a strong performance would have been better.
Wenger sat doubled over, arms tightly folded across his stomach on the bench. He looked like a man in pain. He wouldn’t have been alone, watching this.
So rare were Arsenal’s opportunities that when Olivier Giroud was played in after 78 minutes by Aaron Ramsey, the whole place drew breath in expectation.
Here, against the odds, was the goal that would separate the teams.

Yet Ozil looked a lost soul against Chelsea, his involvement intermittent and rarely to much effect. He played wide on the left but was well marshalled by Branislav Ivanovic. The pair squared up after a high boot from the Serb caught the German on the cheek, but it wasn’t a fair fight. Ozil look as bedraggled as those in the front row as the night wore on.

It was Willian’s chip in the 32nd minute that produced the best football of the half, exquisitely delivered and perfectly timed to fall for Frank Lampard ghosting into space on the far side of the penalty area. His run had clockwork precision, too, and he met the ball on the volley, blasting it against the bar and down, but out.
A minute later, Eden Hazard’s fine run ended with a feed to Fernando Torres but Wojciech Szczesny was equal to his rather underpowered shot. The action finished with a dangerous break from Hazard, knocking the ball in to Willian whose shot was snatched and disappointing.
Nevertheless, Chelsea had more reason to go in at half-time feeling pleased with their efforts. Short of an excellent interception of a Bacary Sagna cross by Gary Cahill, Arsenal had barely threatened, and Giroud had been almost wholly marginalised.

It was, in this way, typical Mourinho. Chelsea’s 0-0 draw at Manchester United earlier in the season had put the padlock on the champions, and here he contrived to do the same to the early front-runners. The fact that in throwing a big blue blanket over the proceedings he also managed to have the best chances just underlined his clarity of thought.
Wenger had not bested Mourinho in nine meetings going into this game; it was easy to see why.
