Sir Alex Ferguson has admitted that he regrets his squad selections for the 2008 and 2011 Champions League finals.
Manchester United reached the final twice in three years, defeating Premier League rivals Chelsea in the first on penalties in Moscow after a 1-1 draw in 2008.
They then faced an outstanding Barcelona side in 2011 at Wembley and were easily swept aside 3-1.
Speaking to MUTV, Ferguson has revealed his regrets over squad choices in both games.
Despite beating Chelsea to lift his second Champions League trophy, the Scot believes not picking Ji-sung Park in his final squad was possibly an error.
“It was a really great bunch of players with a great attitude about them and a good, strong squad,” he said. “My problem in the 2008 final, maybe I even regret it to this day, was I left Ji-sung Park out completely in the final.
“He’d played such a great role and that’s the problem when you get to these finals.”
Ferguson also admitted that Bulgarian hitman Dimitar Berbatov did not deserve to be left out of the squad to tackle Barca three years later.
“At Wembley, I did it to Dimitar Berbatov and he took it badly. He didn’t deserve it,” he said.
“No player deserves to be left out of the final. That’s why we try hard at these European seminars with the coaches to try to get 11 subs in the final.”
