Giggs: Park strike was so vital
Manchester United veteran Ryan Giggs admitted Park Ji-sung's goal "knocked the stuffing" out of 10-man Chelsea as his side beat their rivals to a Champions League semi-final spot with a 2-1 win on the night.
With United holding a 1-0 lead from the first leg at Stamford Bridge, Javier Hernandez crashed home the night's opening goal just before half-time from Giggs' cross.
When Ramires was dismissed for the Blues in the 70th minute, their hopes seemed all-but over.
However, substitute Didier Drogba reduced the deficit in the 77th minute before Park immediately went up the other end to reclaim United's two-goal cushion and end the contest as United won 3-1 on aggregate.
"Chelsea gave us a great game but you're always pleased to get into the semi-finals," Giggs told Sky Sports 2.
"We expected them to come at us, they needed to score, we knew we needed to try to score too, to take the pressure of us.
"I think we deserved it, we played well down there, had a good gameplan and stuck to it and tonight got a couple of great goals.
"The second goal came at exactly the right time, they had just scored, so us scoring so quickly after they had knocked the stuffing out of them, really."
United boss Sir Alex Ferguson said: "I think we played very, very well against a very, very good team. Chelsea played a big part in that game today.
"I thought we were the better team on the night. In a team game we had some fantastic performances, Park, Chicharito (Hernandez), all over, no-one let us down."
Ferguson admitted his side were lucky to score so quickly after Chelsea's leveller on the night.
"That was the break we got in the game, to be honest, I thought it was a cheap goal to lose."
