At left-back, England and Gareth Southgate are currently blessed with a host of quality options to choose from.
The Three Lions boss has the likes of Luke Shaw and Danny Rose who he can call upon, while Fulham’s Ryan Sessegnon is also another choice going forward even if he has been playing in a more advanced position over the last year or so.
The 18-year-old is still a very capable defender and has become a great example for someone such as Adam Lewis to look to.
The Liverpool youngster is highly thought of at Anfield and could eventually make the breakthrough into first-team at left-back like Sessegnon.
With that in mind, how do the two teenagers compare?
It has been a difficult start to life in the Premier League for Sessegnon and Fulham as a whole.
However, there is no denying the talent of the Fulham youth product, who accomplished so much in the Championship last season at such a young age.
From the left flank, Sessegnon scored 16 goals and registered eight assists in just under 50 league appearances as Fulham went on to win promotion, displaying the sort of attacking threat he brings to the team.
As previously stated, though, he can be just as effective when it comes to defending, which has seen him earmarked as the ideal successor to Rose in the left-back position at Tottenham (via the Telegraph), as a result.
Be it at left wing or left-back, Sessegnon has the potential to become a leading player in the Premier League.

While Lewis obviously does not have the same kind of first-team experience that Sessegnon has, he is still a similar kind of player to the Fulham man in terms of style.
Lewis loves attacking down the left flank where he is able to put crosses into the box and play forward passes.
“Going forward, I haven’t seen anyone as good as him [Lewis] at that age in terms of quality and what he can deliver in the final third,” Liverpool legend and Rangers manager Steven Gerrard was quoted saying by the Liverpool Echo last year.
Defensively, there is much room for improvement with the 18-year-old needing to keep in mind his defensive responsibilities, for example.
But that will quite clearly come with age and coaching.
TT Grade: C+
Lewis is on the right path to becoming an efficient modern-day full-back with his ability going forward clear for everyone to see.
The Liverpool man, however, lacks experience, especially compared to Sessegnon, who is of the same age.
Considering such, there is a long way to go for Lewis, though Sessegnon’s example gives him reason to be optimistic about making that step up into the first team.
