It's been another decade of wonderful success for the club. From 2010 to 2019 we have won three Premier League titles, the Champions League, the Europa League twice, the FA Cup three times and the League Cup once, racking up some indelible memories along the way.

Choosing a first XI from players to have represented us over that period is not easy, so we have left it to you, the fans, to decide! We have selected a 4-3-3 formation with all those players with 50 appearances or more from January 2010 to December 2019 eligible for selection.

Yesterday we asked you to vote for your right-back of the decade, and today we want you to choose the left-back.

The three candidates are Ashley Cole, Ryan Bertrand and Marcos Alonso. Cole and Bertrand helped us win the Champions League and FA Cup in 2012, before following that up with the Europa League a season later. Cole also lifted the Premier League with us in 2010.

Marcos Alonso, a current Chelsea left-back, has lifted the Premier League, the FA Cup and the Europa League during his time at Stamford Bridge, as well as chipping in with important goals from defence too.

To place your vote, just pick one of the options in the poll below.
