This is very tame banter, when I was in the British army we did worse than this, pissing in each others pockets comes to mind. When your in a solid group of team mates / unit this sorta thing is as normal as it gets lol
Players like stuff like that on Instagram all the time, don't read to much into it, also we have no idea if he would love to be here or not tbh we chelsea fans just assume every one wants to be here lol
Sorry but this game against, a shite team as u said in different words, CHO was awful, mount was in my opinion fking brilliant. For me this CHO over mount crap should end here.
