UNBEATEN RUN CARRIES ON..

Chelsea are unbeaten in their last 13 Premier League games played on Boxing Day (W8 D5), since a 2-4 loss at Charlton in 2003. No team in Europe’s big five leagues has seen more league goals scored by Spanish players this season than Chelsea (20, level with Real Sociedad). Brighton have lost four consecutive away league games without scoring a single goal for the first time since October 2002. Chelsea have scored 12 headed goals in the Premier League this season, more than any other side.

Alvaro Morata has netted 12 headed goals in the big five European leagues since the start of last season, more than any other player.

Cesar Azpilicueta has assisted Morata for six Premier League goals this season, the joint-most for one Chelsea player to another in a single season in the competition (also Fabregas-Costa 14/15 and Lampard-Drogba 09/10).

Since the start of last season, Azpilicueta has racked up 10 Premier League assists, more than any other defender.
