The South Korea international was forced to have an operation towards the end of last season and now faces a lengthy spell on the sidelines. Park will be part of United's visit to Seoul later this week but, after landing in Tokyo for the first leg of his side's four-match Far East tour, Ferguson revealed the former PSV Eindhoven player will be a frustrated spectator for a while yet. "He will not be available until December or January," said Ferguson. "It is very disappointing news but hopefully we have the squad to cover injuries this year."
