The 32-year-old had to put his own needs before those of his Celtic team-mates in training.
The 32-year-old now has a personalised training schedule devoted to maintaining optimum fitness & performance - and that sometimes means withdrawing from squad practice to work on certain aspects of his individual development.
And Gordon admits that requires a degree of selfishness that ultimately benefits Celtic as a whole, with the goalkeeper's displays having improved as a result.
The shot-stopper has been in fine form since joining Celtic last summer and says his new training regime has gone a long way to ensuring that continues.
“It’s actually better now as it’s focused solely on me and my needs and what I need to do to be able to perform on a matchday,” Gordon told reporters.
“I had to be a little bit selfish in terms of what I need out of my training and just focus entirely on what I need to do.
“Whether that’s coming out of shooting sessions to let younger goalies go in and take part in that because there’s not really a great deal in that for a goalkeeper other than picking the ball out the net.
"I’ve tailored my training better now than I have done at any other part of my career and I’m better for it.”
It is all systems go for Gordon and Celtic at the moment, with Ronny Deila's side still in the hunt for a quadruple, let alone a treble.
Despite a slow start to their league campaign (by the champions' own high standards) Celtic are flying in the Scottish Premiership and travel to Partick Thistle for a 7.45pm kick-off later tonight.
The Bhoys also face Inter Milan in the Europa League later this month and have reached the League Cup final, as well as the Scottish Cup quarter-finals.
