Both Chelsea and Liverpool came away with victories in the Premier Leaugue at the weekend, without starting the full-backs they would consider as their first choice stars.
The Blues struggled to a win over Crystal Palace with Andreas Christensen and Malang Sarr on their flanks, two players more at home in the centre of defence. The Denmark international last took up the role in Chelsea colours seven years ago.
Jurgen Klopp opted to make use of Joe Gomez on the right and Kostas Tsimikas on the left as the Reds overcame a 1-0 deficit to beat Norwich 3-1 at Anfield. Andrew Robertson was on the bench for the German coach, while Trent Alexander-Arnold did not make the squad at all.
