Full-backs are now an essential part of football, in terms of tactics and team structure.
The position that was one considered a home for defenders not good enough (or tall enough) to play centre-back is now a key component on the game.
The Most successful teams boast a huge chasm of quality in full backs positions, and In Trent Alexander Arnold and Andrew Roberston, the “Champions of Europe”, pose the best full backs in world football.

At the moment Robertson is without doubt the best left-back in world football.
Jurgen Klopp is famously known for this 4-3-3 formation. But as a matter of fact the Liverpool boss deploys a 2-3-5 Formation when in possession thus allowing both full backs strive further up the pitch.
And it’s of no suprise after eight premier league games Robertson boast of the player with the most touches in the premier league With an 85% passing accuracy.
Last season in the Premier League, only attackers Raheem Sterling, Leroy Sane, and Eden Hazard had more assists from open play (four of Trent Alexander-Arnold’s came from set pieces),and he was 12th in Europe’s top five leagues for total assists.
Robertson has also picked up from where he left off last Season laying 2assists already, and wining 0.4 of his aerial dues in his eight premier league appearances.
Prior to the Scotman arrival the left back position was a hoodoo to the reds with Series of Erratic displays from the now departed Alberto Moreno.
And the gulf in class between the two players shows precisely how formidable Liverpool defence have elvoved.
The best players in their position are often part of a great team, and that is currently the case with Robertson.
Trent Alexander Arnold
Alexander Arnold may have been robbed of a place in the FIFPro World XI last month by Sergio Ramos, but he has a very strong case for being the world’s best right back.
The Liverpool academy posses similar traits to City’s Midfield Mastero Kelvin De Bruyne in terms of his creative numbers.
The 21 year old represents the pinnacle of Jurgen Klopp full throat attacking football and while there is still room for improvement in a defensive sense, this aspect of his game is much stronger than he gets credit for.
Having initially emerged as a central midfielder in the Liverpool academy, though, there remains a conversation to be had about whether he eventually moves back into that position at some stage further down the line in a similar manner to the likes of Kimmich and Philipp Lahm.
The next step for him should be adding a few more regular goals to his game, as he clearly as the technique to strike a ball with power and accuracy when presented the opportunity to do so.
To be where he is at the age of 21 is truly extraordinary, and the boundaries for what lies head are almost limitless.
We’re witnessing an icon of a generation.
