Robinho was expected to be read the riot act by Sparky after going AWOL from Tenerife last week.
One senior squad member told The Sun: "The whole situation was quite surreal.
"Most of the lads turned up expecting fireworks between the manager and Robbie but there wasn't even a word.
"The boss did not single him out for any kind of treatment - angry or otherwise. It was as if nothing had happened.
"As far as the players are concerned, we're all left wondering what the hell is going on."
