The Dons ran out deserved 2-1 winners at Ibrox earlier thanks to goals from Graeme Shinnie and Ryan Christie.
That win secured second place in the Premiership table and came at the end of a war of words between McInnes and Caixinha.
The Rangers manager said earlier in the week that Aberdeen were coming to the end of a cycle in their squad before McInnes responded telling him that it’s embarrassing for his old team to competing with his new team to finish second.
Now McInnes isn’t allowed in Caixinha’s Ibrox office, according to Clyde Superscoreboard:
Pedro Caixinha says Derek McInnes is not welcome in his office after disrespecting him at Pittodrie last month. DMc says PC is "mistaken"…

It’s not clear exactly what McInnes did at Pittodrie after Rangers won 3-0 there last month, but it must have been something serious if Caixinha is prepared to hold a grudge over it.
Or perhaps the Portuguese manager was just annoyed by McInnes’ words in the press yesterday?
