The young goalkeeper must be hoping to make a breakthrough soon.
Arsenal's goalkeeping situation has caught attention this season. They brought in Petr Cech this summer to be number one, moving on Wojciech Szczesny in the aftermath.
It has moved David Ospina to second choice and Emiliano Martinez has gone out on loan to Wolverhampton Wanderers.
After all of that chopping and changing young stopper Matt Macey has become third-choice keeper at the club.
Yesterday however, ahead of Arsenal's tie with Watford, the stopper was heavily involved in first-team training at London Colney - with Ospina only just returning from his international exploits with Colombia.
The 21-year-old giant, who stands at a sizeable 6 ft 6 ins tall, arrived at Arsenal from Bristol Rovers in 2013 and spent a period of time out on loan with Accrington Stanley earlier this year.
He will obviously hope to go on and become a first-teamer at Arsenal but has so far been on the bench for Arsenal just three times in the Premier League and is unlikely to be in that position again v Watford tomorrow.
Macey will have to continue working hard in training with the hope of one day making his Arsenal debut.
