Arsenal and the Blues shared the spoils after a 0-0 draw at the Emirates and Keown feels the Gunners went too much into their own shell during the second half.
“In the first half Arsenal played at a terrific tempo, especially down the left, but the whistle came at the perfect time for Chelsea,” said Keown.
“After the break Arsenal didn’t move the ball quickly enough. They looked mindful of the Monaco game where they lost control but here there was not enough spark.”
Arsenal are at their very best when they move the ball forward and through their midfield with plenty of zip and pace.
When they get it right, they are very difficult to defend against but that system relies on space and gaps developing in their opposition.
Unfortunately yesterday, the Gunners found it difficult with Jose Mourinho’s game plan for the Blues quite obvious.
Chelsea were determined to avoid defeat by any means, looking to exploit the counter attack and Arsenal seemed wary considering the way they have been opened up on the counter at times this season.
They didn’t do much wrong in the first half yesterday, with a goal one of the few things that was missing over the first 45 minutes.
Chasing a big lead to Chelsea at the top of the Premier League table, why things changed slightly after the half-time break is a mystery as the home side arguably needed the win more.
