Alex McLeish admitted he found it hard to hold back the tears as he bade farewell to the Rangers fans after the win over Hearts.
The out-going Rangers manager said: "I was overwhelmed by the reaction of the crowd. I'm delighted and proud to have been at the centre of that applause.
"There have been so many highs - getting the first trophy was uppermost in my mind having got the Rangers job.
"But it would be difficult to beat the treble," he added.
McLeish insisted he had no regrets about having had to work with a vastly reduced budget in comparison with his predecessors.
"It was a different era, it wasn't possible. I'm proud to have left the club in a better financial state. When you cut the budget and still bring financial success, it's fantastically satisfying," he said.
"I tried to serve the club with the honour befitting a club like Rangers and hopefully people will say I did quite well."
After four-and-a-half years in charge at Ibrox, McLeish concluded by saying: "I've had a great time and I wish Paul Le Guen all the best."
