Top-quality left-sided centre-backs are tough to find in football and Spurs have really landed on their feet with Jan Vertonghen.
Having a left-sided player who is also left-footed is a major advantage when it comes to defending and playing out with their preferred stronger foot.
This is part of the reason why the Alderweireld/Vertonghen partnership works so well at Tottenham, and has done for a number of years now.
However, with Jan now at the ripe old age of 32, Spurs may have to both start looking for a replacement and protect him from injury with slightly reduced game time.
I believe that the solution already sits within Pochettino’s ranks in a certain Mr Ben Davies. Now, as many of you will know, Davies has regularly played on the left side of a back three for both Spurs and Wales, but he has rarely worked in a flat back four.
At 6 feet in height and 26-years of age, I believe that Davies could be the perfect utility player for Poch to rotate in as a second choice left-back and left-centre back in both a back four and back five.
He is a sensible defender, good on the ball, has decent pace, vast experience, and everything a player needs to be a good centre-back in my opinion.
While Foyth and Sanchez look to be great prospects, I am not confident in their ability to play together in a back four, and Davies could be the perfect left-sided option to slot in with one or the other.
This could be especially useful if Foyth does eventually make the switch to right-back and Spurs are left short in the centre of defence.
