Arsenal boss Mikel Arteta is unhappy with their restart schedule.
For Wednesday's clash with Liverpool, Arteta has to pick his players up physically as well as mentally after their north London derby defeat against Tottenham on Sunday.
He said: "Some players have had huge demands since we joined the season and played a lot of minutes and you can see that recovery wise with the schedule that we have been given again by the Premier League, every two and half days to play.
"But we will assess them today and tomorrow and put the players on the pitch that are in the best possible condition to compete and try to win the game again.
"We played 11 games and we only had an advantage in one which was against Spurs. The rest, all the teams had at least 24, 36 or 48 hours more [rest] than us.
"But look at the boys, they keep going, they go full gas it doesn't matter and we will do it again and we cannot complain because it doesn't matter. They are not going to change it. The fixtures are already there so we will keep going and try our best."
