Arsenal had 12 players on the bench against Kairat on Wednesday night as the North London side strolled to a perfect European campaign so far under Arteta.
This amount of top players on the bench gave Arteta a plethora of options to choose from when selecting substitutes.
Compared to the Premier League, this is a big difference, as Christian Norgaard and Kai Havertz are among many players who have missed out on the squad in recent weeks due to restrictions.
When asked about leaving such players out, Arteta responded and revealed that he is pleading to make Premier League squads bigger.
"At the moment there are two or three players who have to be out of the squad, that’s a reality and I cannot change that," Arteta said.
"These are the rules, hopefully the Premier League next season instead of 18 outfield players they will do 20.
"I beg them from here, like it is in the Champions League because it’s much better to manage the squad, to maintain the value of the players, to maintain the mental health of the players as nobody wants to get out of the squad.
"I beg them so between all of us to help us with that. We can deal with hotels, travel and all of that, that would be very, very helpful for everybody. The worst thing is to leave somebody (out).
Some fans argue that bigger squads would only help wealthier teams who can have several world-class players on the bench, aiding rotation and widening the gap in the English top flight.
