Diame was late for a 7am team meeting called by manager Sam Allardyce following last week's defeat at Arsenal.
Nolan wrote for whufc.com: "Mo Diame was a bit late for the 7am meeting that the gaffer called, which does happen with players from time to time! We all had to wait for him before we could start and when he arrived, we all gave him stick for not only being late and keeping us all waiting, but we said we thought he had left us without saying goodbye!
"As everyone knows, there is a lot of speculation in the media about Mo, so we thought we would give him more stick about that! To be fair to him, he took all the banter really well and joined in as part of the group as we discussed everything from the match and looked ahead."
