Today, Alexander-Arnold could become the 114th Liverpool player in history to reach the landmark of 200 appearances in all competitions and the fourth youngest to reach the milestone (23 years, 88 days).
He will be behind only Michael Owen, Robbie Fowler and Phil Thompson.
A low-scoring fixture
Liverpool have scored 23 times at Stamford Bridge in the last 29 league visits, with the 3-1 win in October 2015 being the only occasion they have managed more than two goals since 1989.
However, they have at least scored in 11 of the last 13 league meetings at the Bridge after netting in just five of the previous 16.
The Reds have won their last two at Stamford Bridge. They’ve not won three in a row in the league there since August 1974.
Following his two goals here last season, should Sadio Mane score today, he will become the first Liverpool player to score in successive Reds league visits to Chelsea since Jack Balmer did so in January 1947.
Chelsea have dropped 11 points from winning positions in the league this season – more than they did in the whole of last season (10).
Meanwhile, Chelsea have kept one clean sheet in their last eight top-flight matches.
At home this season they have won five of nine in the league – taking 18 points out of 27. They have picked up more points away from Stamford Bridge (23) than at home (19).
But their sole defeat on home soil came at the hands of Man City in September (1-0) and are unbeaten in 10 at Stamford Bridge in all competitions since.
Anthony Taylor has refereed games between these teams three times previously – Liverpool are yet to win any of those, with two defeats and a draw.
The draw was the 1-1 at Anfield last August.
He has issued four red cards in 14 Premier League games this season including Reece James and Paul Pogba against Liverpool.
