I still think Tottenham is going to have problems holding on to those values. Rose and Walker are great examples. They are homegrown English fullbacks. Every top four team needs homegrown players for the CL and fullback is a weak position for many teams. If Man City is willing to pay what they did for Stones, what will they pay for Walker, who is closer to the finished article?
So Spurs are either going to have to blow up their salary structure, because these guys can make 100 to 150, 000 pounds a week elsewhere, or they're going to be a selling club.
Just going through the roster:
Kane -- Definite interest from bigger domestic teams, probably some continental interest.
Dele -- No brainer for any top four domestic team. Interest as far up the ladder as Real Madrid
Dier - Definite interest from bigger domestic teams
Rose - Ditto
Walker -- Ditto
Lloris -- Could easily see a PSG bid. A top tier keeper on an affordable salary. You'd think that Liverpool would kill to bid on him. If Real Madrid starts the keeper dominos falling, he could easily end up replacing whoever Real poaches. Could also be a Pep target if Bravo continues to struggle.
Kane - already on 100K+ (with incentives)
Dele - will get a new deal this summer, not going to a domestic team, eventually will end up in Spain
Dier - One of the most important players for Spurs - he will get his money, and be a future captain.
Rose - Rose has an unusually strong relationship with Pochettino. If Spurs keep Pochettino happy, Rose will be happy.
Walker - has said in the last few weeks that he hopes to retire at Spurs.
Lloris - I think he could end up back at PSG to end his career, but I get the sense that his wife likes London.
You keep talking about Spurs having to "Blow up" their salary structure as if they won't do that. They have given new contracts to key players (excepting Lamela, who is not currently in the starting XI when healthy). They have signed Pochettino to a new deal - and he is the lynchpin to the squad cohesiveness. It is as close a squad as I have seen in nearly any sport (albeit I don't watch any other team as closely as I watch Spurs). They generally like playing with each other, and for Pochettino. Spurs are also fortunate not to have any true mercenaries on their roster right now.
When I look at the squad, I don't anticipate any of the starters to leave in the next few years. Dembele would be the one exception I could see if China comes in with a big bid, for a big pay day. Spurs have not sold to a "bigger" domestic club since 2008, and they are unlikely to do so for financial reasons now.
With the new TV revenue, and upcoming stadium revenue, Spurs won't have to sell anyone they want to keep. Spurs also have the advantage now of being able to spend transfer money on new deals. There are no gaping holes in the line-up that require a big spend - they will continue to rely on continuity, and natural progression by the players to improve, as they are still the youngest squad in the league. They are on pace this season to improve on total points for the 3rd year under Pochettino. Having said that, the goal here is to win something - and this team will need to win a trophy or 2 in the next couple of years to keep everyone together long-term.
Of the players currently on the roster - most likely to leave: Bentaleb (on loan at Schalke); Fazio (on loan at Roma); Sissoko, Lamela (says he wants to stay - but if Spurs can get Isco this summer, Lamela will be sold - I don't think they can get Isco); Wimmer - back up to Vertonghen, but not comfortable in a 3-back system; Davies - back up to Rose, but not good enough as a wingback - could stay as a back-up to Vertonghen. All of those would be sold as surplus to requirements, or to bring in a better replacement. Nobody is agitating to leave (except Bentaleb) - that has been Spurs biggest problem the last couple of summers - convincing some of the fringe players to leave.
And the cupboard is not bare coming from the Academy - Winks has developed into a good squad player this season, I expect Carter-Vickers to have a bigger role next season. And, we will start to see a few appearances from Marcus Edwards, who will be Eriksen's heir apparent down the road.
Spurs don't have silly money to spend in the transfer market (or on wages), but they have enough money to stay competitive. And right now, I would not trade the starting XI for Spurs: Lloris, Dier, Alderweireld, Vertonghen, Walker, Wanyama, Dembele, Rose, Eriksen, Dele, Kane with any roster in the league.
