So his warning that manager Ally McCoist had to win a major cup competition this season in order to hold on to his job is now meaningless.
Yet, McCoist's team now looks far more capable of achieving cup success than at any time during Green's turbulent tenure.
His new-look side's performances in SPFL League One so far during the 2013/14 campaign have been nothing short of devastating.
To date, Rangers have played four games, won four games, scored 18 goals and conceded just one goal in their division.
Significantly, each of those victories was achieved while fielding only two of their new players as unregistered trialists.
The signing ban imposed by the SFA for the non-payment of over £13million of PAYE, NIC and VAT during the Craig Whyte era has now expired. And Cammy Bell, Nicky Clark, Jon Daly, Ricky Foster, Nicky Law, Arnold Peralta, Bilel Mohsni and Stevie Smith put pen to paper with Rangers today.
They will all be able to start a game for the first time in the League One meeting with Arbroath at Ibrox on Saturday week. It will be very interesting indeed to see how Rangers fare with all eight of the summer acquisitions actively involved on game day.
If they can steamroller part-time opposition in the third tier with just two new faces in the starting line-up then the likelihood is they will do better. Much, much better.
Winning the league will - although nobody at the Glasgow club will admit as much publicly - be a formality this season.
Going on an extended run in the Scottish Cup is also an achievable goal given the clear quality of this side.
"We have now got all of the new boys available and they will certainly strengthen the team and the squad," said McCoist, whose team is now three points clear of nearest challengers Dunfermline and Stenhousemuir.
"Outwith the poor performance in the League Cup at Forfar, we have started the season reasonably well. But that is all it is. It is just a good start.
"But with the squad we have got now we should have the same hopes and aspirations as other clubs in the top league outwith of Celtic.
"The likes of Hearts, Hibs, Dundee United and St Johnstone are all very hopeful of a cup run. I would count ourselves in that category.
"I don't think we should be expected to win a cup, but we are more hopeful of going on an extended run this year than we were last year."
If Rangers continue to finish as clinically as they did in their 5-0 rout of East Fife at Ibrox on Saturday then most opposition teams, including those in the top flight, will struggle to contain them.
Nicky Clark showed tremendous composure and technique to net on his competitive debut after just 30 seconds.
The 22-year-old, who had not played a serious match in four months, will have gained great confidence from making such an encouraging start to his Rangers career. More goals will surely follow.
And just what exactly can be said about Lee McCulloch that has not already been said before? The club captain scored a hat-trick of headers, a feat not even his manager pulled off in his playing days, against the men from Methil.
His personal haul was all the more remarkable given that, before the weekend, he had been played at centre-half.
Elsewhere, Lewis Macleod hit his third goal in three league games. The dipping volley from the edge of the visitors' area was the best of the lot, too.
McCoist said: "I thought the level of finishing was excellent at the weekend. I was especially delighted for Nicky to score so early in his debut.
"He has been showing in training that he will score goals. He plays on the shoulder, he runs through, he is extremely quick and has a wide range of finishes. And Lee was absolutely terrific. It was a brilliant hat-trick. I was very surprised to learn it was his first hat-trick for Rangers."
Despite the emphatic win, the fans in the BF1 section of the Broomloan Road stand directed unsavoury chants at the club board once again towards the end of the game.
It was a reminder, as if one was needed, that no matter how much progress is being made on the field of play, all is still not well elsewhere at Rangers.
McCoist declined to comment on the departure of Green - who has apparently sold his stake in the club to Greenock businessman Sandy Easdale - from Rangers.
"I need to look forward," he said. "I just want to deal with what is happening out on the park."
However, it is clear that with Rangers now having seen out their signing ban and clearly making huge strides forward in many important areas, the need for unity at the top level is greater than ever.
