Who do you think's most likely to carve a senior Spurs career, mate?
Troy, Dane, Veliz, Lankshear......
At this point in time its really tricky to say, and despite all having something going for them, the answer might be none of them !
Troy, now aged 22, and physically developed, has had his most successful campaign in Dutch League, but it would be a big step up to get into Spurs squad, so imo he'd have to convince Ange he could help by having a good pre-season at Spurs - and if so be could take a Club Trained position in EL squad and could act as a sub and/or emergency striker and we could see if he might make it at Spurs. But in truth I think he needs another year on loan playing football as the main striker somewhere to continue to develop and show this season was not a one off.
Alejo is next oldest and will be 21 in September, so could be considered an u21 in PL next season but would be considered an overseas trained player in EL. I can't see him getting enough game time to develop in PL alone, so I think his best route would be a loan for a year, but the following season he'd need to compete for one of the 17 overseas trained player places in PL and EL - so he's really got to do enough next season to show that or be loaned out again.
Dane is next oldest, only just 20, and still counts as an u21. He's not played that much recently but got called up to E u20's in March and scored a hattrick against Poland u20's and then 2 goals in 30 mins in the following match against Czech u20's a few days later, so appears not to have lost his ability to step up and score goals which he's always been good at. Again he needs to impress Ange in pre-season if he's going to stay with Spurs squad next season or if he needs a loan for a season.
Will is the youngest, only just 19, and joined 2 years ago on 31 August (ie after season started), so Spurs might want to keep him at Spurs for the first half of the season, so that he meets List B criteria in EL - and if that's the case I imagine he'd play u21's and likely spend time on Spurs first team bench. If not he'd be loaned out, likely to a L1 side where I think he'd do fine as he's quite a 'unit' and scores goals provided he's playing with a goal creator, and following season probably go to Championship. He still has youth on his side and this year is top scorer in England's PL2 (u21 league) so will (no pun intended) have been noticed by clubs wanting to loan in youngsters.
So all could have a pathway to get to Spurs first team, Its just a question of showing they can play and score goals largely on loans in lower leagues and impressing Ange in pre-season games - but its not going to be easy for any of them.
