Man Utd boss Ferguson happy with Park return
The South Korean international, 26, has recovered from a knee injury sustained in March and following successful surgery is back in full training with the Premier League champions.
"His training has been excellent in the last few weeks, well beyond what we expected," Ferguson told reporters.
"When players have been out for nine months you are waiting for a slow recovery in some cases.
"But since he has come back in amongst the players he has been terrific so he will take part in the Christmas games. Which one depends on a lot of things, of course."
