(Updates with U.S. shares)

LONDON, Dec 18 (Reuters) - Manchester United shares climbed after the Premier League soccer club sacked manager Jose Mourinho, an indication investors welcomed the move after a dismal start to the season.
Manchester United's New York-listed shares were up 4.2 percent by 1500 GMT, their first gain in a week, and had traded 20 percent of their average daily volume in just 45 minutes.
Mourinho's relationship with Manchester United reached the point of irretrievable breakdown a long time ago but the club finally served the divorce papers on Tuesday following one humiliation too many.
The stock's Frankfurt listing - which is secondary, and less widely traded - had climbed 1.4 percent earlier in low volumes after extending gains following the news. (Reporting by Helen Reid; editing by Josephine Mason)
