Di Matteo never did feel his club's stalwarts were past it.
"We've had a difficult season and a lot of criticism," he said.
"But the players responded today to all the adversity we've faced.
"The answer was today on the pitch. The football is always the best way to deliver the answer."
Didier Drogba became the first player to score in four finals, John Terry became the first captain in the modern era to lift the trophy on four occasions, while Ashley Cole was collecting an incredible seventh winners' medal.
"He's not 65. He's a top professional," Di Matteo said of Drogba's contribution.
