@twosips spot on in his latest video regarding Brahim. Only thing I disagree with him on is that Guardiola could've done more for him and isn't free from any blame if you just isolate the whole situation with Brahim.
I don't really think Guardiola is free from blame, I just don't think it's unreasonable that Pep took Mahrez cos he was offered him. *Any* manager in world football would in my personal opinion. That's not great for Brahim, no, but I think that's just the game really.
