Former Manchester United manager Sir Alex Ferguson has revealed he regrets not deploying Park Ji-sung to man-mark Lionel Messi in the Champions League final between Red Devils and FC Barcelona in 2011.
Barcelona claimed their fourth Champions League title with a 3-1 win over Man United in that match, with Messi and David Villa scoring in the second-half after Pedro and Wayne Rooney had bagged a goal each for their respective teams in the first-half.
And, Ferguson believes if he had played Park against Messi, they would have beaten the Catalan giants in the final.
"That's where I lost the final against Barcelona at Wembley," Ferguson told Gary Neville in an interview with the SportBible, when the latter recalled the South Korean midfielder was often the manager's go-to player for specific man-marking job.
The legendary manager added: "I should have changed at half-time and put Ji-sung Park on Messi. That was a mistake... I was going to do it at half-time, then I said, 'Well, we just equalised before half-time, they may see the game differently, we may grow into the game better.'
"We were actually quite good in the last 10 minutes of that half. We came into it and we could have been in front.
"But if I'd played Ji-sung Park against Messi, I think we'd have beat them. I really do."
