Mickey Harte paid tribute to Peter Canavan after the Errigal Ciaran star held his nerve to send the Red Hands into the All-Ireland Football Final.
The two teams produced an enthralling contest at Croke Park
"If anybody needs to take a pressure kick like that then Peter Canavan is the man. Thank god for men like Peter Canavan," said the Tyrone boss.
Harte added that he would have content to earn a replay a replay after Steven McDonnell's 59th minute goal.
"It looked as though we were going out at that stage."
However, Harte added that he was delighted that his team would have three full weeks to prepare for the All-Ireland decider against Kerry.
"We've had a long hot summer and maybe we deserve those couple of weeks."
As Harte was speaking in the tunnel area, wild Tyrone celebrations were in full swing out on the pitch but the Tyrone boss pointed out that "there are no cups today".
"Enjoy the moment but know there is a lot more work to be done if we want to lift the Sam Magure Cup."
Armagh boss Joe Kernan couldn't hide his huge disappointment after seeing his side denied in injury-time.
"Two of these best teams in the country gave it everything for 72 minutes, non-stop to the end," said the Crossmaglen man.
"We thought that we had it but we gave the ball away a few times and Tyrone came up the field and punished us."
Kernan described the injury-time free conceded by wing-back Ciaran McKeever as "the killer".
The Armagh manager said his team's failure to hit the next score after McDonnell's goal had been crucial.
"Tyrone came back down the field straight away and got a point.
"You get the rub of the green some days but today we didn't."
Despite the advancing years of the some of the Armagh squad, Kernan insisted that Armagh will be back for another tilt at Sam Maguire next season.
Whether Kernan will be involved is not guaranteed because the Armagh boss said that he will take some time before deciding his future with the county.
"Those Armagh players owe nobody nothing.
"We're out of the All-Ireland and it's disappointing. But chin-up. These players will be back."
Armagh team trainer John McCloskey was clearly unhappy with Russell's decision to award the decisive free - although TV replays suggested that Ciaran McKeever had grabbed Stephen O'Neill's arm.
"It was a life-changing decision if you like," said McCloskey.
"It changes everybody's lives. Tyrone will go on and hopefully win the All-Ireland while we've got to go back to lick our wounds."
