Interesting video doing the rounds on twitter.

ASM talking to the camera and Gayle walks past, then Dwight Gayle in a sarcastic tone "the saviour is back" towards ASM.

ASM doesn't look to impressed, then Atsu says something and ASM akwardly laughs.

Now it could be one of several things to my mind.

1 - A dig at Bruce, ASM laughs akwardly because he doesn't want to get caught up in it.
2 - A dig at ASM, hence the not looking impressed.
3 - A dig at Bruce but ASM doesn't realise until Atsu explains in French.

Either way, it's not a good look and I'd say the squad is now properly riven into groups.
