Celtic goalkeeper Craig Gordon admitted he was glad to get something to do in the second half of his side's 4-0 William Hill Scottish Cup semi-final victory after his quietest 45 minutes of action against Rangers.
Yet, no matter what winning the Old Firm is something of great.
Tom Rogic and Callum McGregor netted in the first-half and the French double-act of Moussa Dembele and Olivier Ntcham scored penalty-kicks while the Ibrox side ended with 10 men following the sending-off of Ross McCrorie.
McManus is still doubtful as to whether the bids really arrived and says whoever rejected them on behalf of Rangers should be chased out of Ibrox.
But he urged his players to use that emotion to ensure a positive response next Sunday against Hearts, as Rangers - second in the Premiership on goal difference from Aberdeen - begin their final run of five matches, including facing Celtic again on 29 April.
"Rangers caused their own problems". I asked them to get into a shape and the structure was there to allow them to press but, when it comes to the game, you have to get up closer to your opponent than we did in the first period. When you have the amount of bodies they do in the middle of the pitch you want to show them in the pitch. The wingers should have been outside and showing them inside into the congested area. "We train every single day and the energy levels are there but we were second best in nearly everything today - second balls, first balls, it was just unacceptable for Rangers".
"Take nothing away from Celtic, they were outstanding from start to finish, but I think Rangers have got massive problems ahead..."
"I was quite happy with the workload, especially after going an hour with not doing very much at all".
There is also uncertainty over the future of Murty after chairman Dave King released a statement which gave little reassurance that he would still be in charge next season. "Honestly, I can't tell you", he said.
Celtic were simply playing at a higher tempo and in the 32nd minute Ntcham fired just wide from the edge of the box. This was a Celtic team in full flow, confident, arrogant, a joy to watch.
