William Saliba and Gabriel Magalhaes have struck up the most formidable of centre-half partnerships, while David Raya is a Golden Glove-winning goalkeeper. As a unit, they are notoriously difficult to breach.
Arteta told reporters of seeing a fifth successive clean sheet in all competitions picked up against Palace: “I just told the boys that I value more this victory than any other victory this season. Because we knew the difficulty of it, you come after playing every three days, you have a big opportunity as well with the things that happened during this weekend and I knew, you know, we play against a team that in my opinion has been one of the best recently in terms of organisation, how difficult they made it, how frustrated they can make you and the moment that you lose that concentration they will punish you for sure.
“And we have managed to be very stable, playing the game that we have to play. In the first half a bit stuck, we found a way to score the goal in the second one, we attacked better and we were more fluent. But with 1-0 we knew that we had to suffer because it's a team that has to score goals against any other opponent this season, so to keep the clean sheet is very, very important.”
The Gunners have not conceded more than one goal in any competitive fixture this season. That ensures that they are always in with a chance of taking something from any given game. That has been the case for some time.
