Since the turn of the century, current Barclays Premier League leaders Chelsea have been previously top at Christmas on three occasions - in 2004, 2005 and 2009 - and gone on to win the title.
On Monday, Chelsea won 2-0 at Stoke to lead the table by three points, and they return to Stamford Bridge, where they have a perfect record, winning eight out of eight and scoring 20 goals and conceding just three, easily the best record in the division.
And Chelsea's Boxing Day record is good; their last Boxing Day defeat at Stamford Bridge was back in 1995, against Wimbledon.
Now they have another London derby against high-flying West Ham, whose 2-0 win over Leicester City last Saturday means they go into the Christmas period in the top four for the first time in the Barclays Premier League and first time in nearly 30 years.
West Ham have lost just once in their last 11 games, at Everton a month ago, and are now unbeaten in their last five league games, winning four and drawing one.
However, West Ham's record at Stamford Bridge is poor. They last won there in the BPL in September 2002; in eight subsequent visits, they have lost six and drawn two. Indeed, they have failed to score in their last three games, though they did force a goalless draw last season.
