Chelsea face a London derby at Crystal Palace on Saturday looking to keep their slender lead at the top of the Premier League table, with an impressive record against the Eagles. Jose Mourinho’s men are one point clear of Liverpool – who face Tottenham Hotspur on Sunday – and three points clear of Manchester City, who face Arsenal in tomorrow’s late kick-off. The good news for the Blues is that they have never lost to Palace in the Premier League, last losing to the Eagles 12 games ago in 1990. They have won their last five meetings with Palace, and won on their last three visits to Selhurst Park without conceding a goal. The bad news for Chelsea is that every time Palace have been in the Premier League, no one same side has lifted the title at the end of the season, and Chelsea have had their turn. In four previous Premier League campaigns for Palace, Manchester United, Blackburn Rovers, Arsenal and Chelsea have won the trophy, with Manuel Pellegrini’s Man City and Brendan Rodgers’ Liverpool standing by to make it five. The Blues though are coming off the back of last week’s 6-0 demolition of Arsenal, while Tony Pulis’ side have not won in five games, failing to score in their last three.
