Arsenal captain Martin Odegaard misses the trip to Brentford through an injury he picked up last week.
The 23-year-old midfielder suffered a knock in training last weekend and was not able to work as would have been liked ahead of the trip across London.
The Norweigan international has returned to training, but was not able to prepare for Sunday’s trip to west London, according to The Athletic.
Odegaard has only missed four games previously for Arsenal through injury when he was out in April 2021 with an ankle problem.
