The full-back, on-loan from French club Rennes, was Celtic's unlikely Hampden hero by prodding home the only goal of the game in the 84th minute.

This meant Gordon Strachan's team added the Cup to their Scottish Premier League title this season and ended captain Neil Lennon's seven year career with the Glasgow club in style.

But the result was tough on Stephen Kenny's Dunfermline who had been the better side for large periods of the final.

Strachan praised the Pars for their attacking mentality but believed his team deserved the victory.

He said: "Last week at the English FA Cup final you had two teams who were desperate not to lose. Today you had two teams desperate to win and it was a good game.

"I have the greatest respect for what Stephen Kenny is trying to do and when I noticed they were playing a 4-4-2 I knew it was going to be a good game.

"They had a go at it and had the best chances early on but I thought we had the better chances in the second half.

"The longer the game went on the stronger we looked while they were tiring and we deserved to win in the end."

The late winner for Celtic piled more misery on Dunfermline after their relegation from the SPL.

Kenny, however, was happy with his players' efforts, although he admitted Celtic were worthy winners.

The Dunfermline manager said: "Before the game you're looking for your players to express themselves, to be strong and not be too respectful to your opponents.

"We did that, passed the ball really well, retained it well and had a couple of chances.

"But in the second half we didn't retain it as well as we could have and Celtic started creating better chances.

"We hung on and I can't fault any of our players for their efforts, they were terrific, but overall I can't really complain as we were beaten by a strong side."

The Pars had ignored their pre-match billing as underdogs to dominate the opening period.

Jim McIntyre played strike partner Mark Burchill through on goal in the fourth minute only for the former Celtic player to pull his left-foot shot wide from 10-yards.

In the 31st minute Celtic created the best chance of the match so far when Kenny Miller's cross found Jan Vennegoor of Hesselink free six-yards from goal but the Dutch international striker headed wide.

Dunfermline were continuing to press Celtic back at the start of the second half, without really troubling Celtic's Polish goalkeeper Artur Boruc, but it was the SPL Champions who continued creating the best chances.

Aiden McGeady skipped past the Par's French defender Soulemayne Bamba in the 52nd minute before crossing for Miller, who was unmarked eight-yards out, but his header was too close to De Vries who saved low to his left.

Celtic had their best move of the game in the 62nd minute.

Full-back Lee Naylor drove in from the left, played a one-two with Vennegoor of Hesselink and sent a vicious volley towards goal from 18-yards which forced De Vries into a fine reaction save.

With extra-time looming Celtic went on to score a sensational winner from the most unlikely of sources.

Doumbe played the ball out wide to Craig Beattie, who had replaced Miller in the 55th minute, and the substitute drilled it back across goal where the Cameroon international slid in to poke the ball beyond De Vries and into the net.
