Southampton currently have a significant number of players in their squad that have worked their way through the youth system at the club such as Theo Walcott and James Ward-Prowse, who have a total of 648 Premier League appearances between them.

One other player currently in Ralph Hasenhuttl's squad that has made his way through Southampton's youth academy is centre-back Jack Stephens, who currently has 114 league appearances under his belt.

Looking at him, in particular, the 27-year-old defender made his senior debut for the Saints back in January 2012 in an FA Cup victory over Coventry City before making his Premier League bow for the club in their 3-0 defeat against Everton in January 2017 under former Southampton manager Claude Puel.

Overall, Stephens has made 139 appearances for Southampton across all competitions, chipping in with six goals and five assists along the way after working his way through the club's youth system after signing from Plymouth Argyle in a deal worth a reported fee of £150k back in 2011.

So far this season, Stephens had played 90 minutes in all of Southampton's Premier League games before picking up a serious knee injury during their 0-0 draw against Manchester City, ultimately ruling him out for 12 weeks according to Hasenhuttl, which is not only very unfortunate for the player, but for the team as a whole given how prominent he was for them beforehand.

In terms of his market value, in February 2017, shortly after making his Premier League debut for the Saints, Transfermarkt had his value listed as £675k, whereas it now stands at £7.2m, highlighting a significant rise over recent years.

This also shows just how much of a good purchase he was all those years ago for such a low price and how much the club have developed Stephens, who has previously been described as "excellent" by former Saints captain Steven Davis, to become a regular first-team figure for them.

Looking ahead to the future, if Stephens can fully recover from this unfortunate knee injury and get back to playing regularly for the Saints, we see no reason why his market value can't go on and rise even further than it has done recently.
