Manager Mikel Arteta is pushing his players to give more as they seek to win their first league title in 20 years.
Post-game, Saliba said: I'm a little bit tired, but now we have to play with our head as well. We have to push in our last five games and will rest after.
Of course the schedule is brutal yes, but that is football you don't have a choice. You have to play, it's a high level but that's it.
I need a bath and massage! We do our best, but it's more mentally I think because our legs are tired but that's okay, it's football. We have to play with our head and that's it.
Of course we have some good experience from last season and this one as well. It can be up and down quickly so we are well prepared. That's why it's more mental. We have to push and give everything we have. It's a very big week against Chelsea and Tottenham and I hope we will win."
