Three defeats in a row and a top-four finish is starting to look unlikely and for the third game running the defence conceded three goals.
There were mitigating circumstances, in particular, the harsh sending off of Ainsley Maitland-Niles but even so, it has not been a good day for Arsenal.
Leicester deserved their win, no point saying otherwise and if it was not for Leno we could have lost by more than just three goals.
Player ratings
Leno 8
Definitely the Arsenal man of the match, a much better performance than against Wolves and he was the only player that did not deserve to be on the losing side.
Maitland-Niles 4
I thought that his sending off was harsh but off he went and his rating reflects that.
Mustafi 4
It was a little surprising that he was named in the starting line up and Emery was not vindicated in picking the German who put in yet another poor display.
Sokratis 4
Another poor game and he was made to look pedestrian on more than one occasion.
Kolasinac 5
Never made any glaring mistakes but he was often beaten for pace and looked out of his depth at times.
Mkhitaryan 5
Offered nothing really, he did help out in defence a bit more in this game and that is a plus but that is about it.
Torreira 5
Looked busy but did not actually offer anything, we needed him to take control of the midfield and he failed.
Xhaka 5
Same as Torreira, he looked busy but failed in his job which was to take control of the midfield.
Iwobi 4
Had opportunities to sway the game in our favour and came up short and it is not the first time either.
Lacazette 5
Another player that wasted an opportunity and despite running here there and everywhere did not have an impact on the game and was deservedly subbed.
Aubameyang 5
Looked a lost man throughout the game which is not surprising considering there was no service.
Subs
Koscielny 5
Tried his best when he came on but looked just as ragged as his fellow defenders
Guendouzi 5
Another trier but that is about it and was part of a midfield that was simply outfought and outplayed.
Nketiah 5
No better and no worse than Lacazette who he replaced and therefore the same rating.
The ratings are low for most of the players and for me, that is justified, we deserved to lose and lose we did.
