Sims has received many plaudits for his outstanding debut display in the 1-0 win over Everton at the weekend.
The 19-year-old stood out as he set up Charlie Austin's winner within a minute of the game starting, and caught the eye for much of his outing prior to his withdrawal in the closing stages.
He looked a constant threat and was confident with the ball at his feet, and given the opportunities that are being given to younger players by Saints boss Claude Puel this season, Sims wants more game time, admitting that younger players are gaining confidence because of Puel's willingness to give them a chance.
Sims is quoted in the Daily Echo, saying: "It just gives every youngster confidence, because you know if you train and play well you will get a chance.
"I’ve been in the squad but never made it onto the bench, so it’s just getting the chance.
"I went straight into the starting eleven, which was a bit of surprise to me."
He dealt with that particular surprise very well, and considering Southampton's fixture schedule has been pretty busy so far this season the chances are that there could be more game time to come.
The Saints have a huge EFL Cup quarter-final away to Arsenal tomorrow night, where Sims will probably hope to be in contention for selection again.
But there could be other opportunities with the festive season fast approaching, as there are seven Premier League games in December, as well as their huge Europa League clash with Hapoel Be'er Sheva, where the Saints will look to make it through to the knock-out rounds of the competition.
It seems that many fans are looking forward to the prospect of seeing him in action again in the near future.
