Along with other Premier League sides, Tottenham have submitted their squad for until January. Here we look at the younger players who may have an effect on their season.
There are some noticeable names on the list of under-21 players this season who featured last term under Andre Vilas-Boas and Tim Sherwood, as well as a couple of new signings that came in during this window under Mauricio Pochettino, and have already featured this season.
Here is a look at five who could have a telling impact on Tottenham's season:
He was thrown into the side in the second half of last season by Tim Sherwood, and off the back of a pretty good World Cup with Algeria, Bentaleb's profile is growing. Pochettino has also shown he isn't afraid of using the youngster, and he has shown signs of good composure in the middle of the park at such a young age.
Kane was used more and more as the season reached its conclusion last term. Emmanuel Adebayor is the number one striker at the club, but there are reservations about Roberto Soldado. Kane has had opportunities in the Europa League so far this season and has done himself no harm by getting on the scoresheet. If Adebayor were to be unavailable for any games, Kane could be the man tasked with leading the line.
You could argue that Dier has already made a big impact on Spurs this season after signing from Sporting Lisbon, by scoring a last minute winner against West Ham United on the opening day of the season. He has appeared in all three Premier League games so far, and it's clear that the Spurs boss has a tremendous amount of faith in him
Another summer signing, but left-back Davies may be used a little more sparingly than Dier. Danny Rose looks as if he's the first-choice left-back but Davies will certainly get his opportunity to shine in the Europa League, and will provide fierce competition for Rose.
A 19-year-old defender that saw plenty of action during pre-season and can play both as a central defender and a holding midfielder. He has made two senior appearances for the club so far and could be in line for more if the opportunity should arise. He is most likely to feature in cup games, or in late cameo appearances.
