Left-backs are one of the most important players on the field. They are vital and without a quality player in that position, a team is unlikely to enjoy much success.
Now, I have compiled a list of five left-backs, but there is one golden rule: only one left-back from each league in Europe.
5. Domenico Criscito | Zenit St. Petersburg
The Italian left-back, who currently plays for Russian outfit Zenit, is one of the most underrated players ever. He is versatility has been proven many times, and without him Zenit would be absolutely nowhere. He is one of the secrets to their solid defence and pacy attack.
4. Yuto Nagatomo | Inter Milan
With stamina like an engine, the Japanese defender is a work-horse. He runs up and down the field, constantly defending or attacking. He can even play as a winger, too. That's how interchangeable he is. The Inter man has incredible speed and somehow manages to play the full 90 minutes, despite the amount of running he does each match.
3. David Alaba | Bayern Munich
The Austria international is simply bursting with talent. His vision, speed and ability to pop up with a goal sees him make this list. He has been amazing for the the recently-crowned German champions Bayern Munich and is only 20-years-old. He is certainly destined for greatness and is definitely a man to watch.
2. Marcelo | Real Madrid
Now, I had a dilemma between Barcelona's Jordi Alba, Real Madrid's Fabio Coentrao and his team-mate Marcelo, but the Brazilian came out top.
His defending and flair makes him an exciting player. His incredible runs down the flank and his partnership with Cristiano Ronaldo is divine. Marcelo's mix of technical ability with passes and his speed puts him ahead of Alba and Coentrao by a whisker.
1. Ashley Cole | Chelsea
Ultimately, it was a battle between Everton's Leighton Baines and Ashley Cole, but the latter's impressive resume, his consistently excellent form and his speed means it's he who occupies pole position in this list.
He is one of the main reasons for Chelsea's Champions League success, and is amazing. His superb speed and his international experience is excellent. Having played 100 games for England, he qualifies for this list. Both have had great seasons but Cole comes out top.
