Rodallega & N’Zogbia’s celebrations towards Bobby could have been one of 2 things:
1) a show of solidarity with the manager or (with Rodallega) a sign of thanks for sticking by him after recent poor form & his strop against Chelsea – especially in light of Bobby’s public backing of him in press conferences (regardless of the rollocking I suspect he may have got behind closed doors)
or
2) (more so in Rodallega than N’Zogbia’s case) a taunting/pish take of Bobby in a “i’m the only forward you’ve got who can actually score goals” way
I like to think its the first but its not unknown for plenty of players to have done the second one
