Soccer: Tube strike puts matches in doubt

Both English Premier League matches in London on Boxing Day are under threat, as a result of a planned strike by underground drivers.

Arsenal has sold all 60,000 tickets for their match at home to Wolves, but access to the Emirates Stadium could be hampered if the 24-hour strike that day by the drivers' union, goes ahead.

Chelsea's west London derby against Fulham could also be disrupted by a shutdown of the 'tube'.

London mayor Boris Johnson is pursuing a legal challenge against the strike.
