Gary Neville has told Tottenham to learn from the mistake of selling Gareth Bale and keep star players Harry Kane and Dele Alli for at least two more seasons.
Spurs secured a second-place finish in the Premier League by defeating Manchester United 2-1 on Sunday, Kane following up Victor Wanyama's header to secure victory in the club's last game at White Hart Lane, four years after selling Bale to Real Madrid for EUR100million.
And former United star Neville thinks Tottenham would be wrong to accept a huge transfer fee for Kane or Alli at a time when they are set to play at Wembley next season before moving into a new stadium from 2018.
"They have to hang on to two or three players," Neville told his Sky Sports podcast.
"Dele Alli and Harry Kane have to stay at this football club in this next 18 months to two years because the message when they go back to White Hart Lane is that they want people to pay more money and fill that stadium every single week.
"They have to keep those players. They will keep those players. It's a short-term investment to think you can pull in £50m, £60m or £70m for Kane and Alli but the reality is you never replace them.
"They went through that before with Gareth Bale and it took them three or four years to get over that."
However, Neville believes keeping manager Mauricio Pochettino is even more important given what he has achieved for Spurs.
Neville added: "The third person they need to keep is the manager. He is probably number one because he is an absolutely fantastic manager.
"They are going to need 20,000 more people every week to fill the [new] stadium up. I know they have got a long waiting list for season ticket holders but it can go backwards quickly.
"Those three are key to go into the new stadium and I think it's impossible that Daniel Levy will send a message to the fans, to the football club, that we are retreating going to Wembley next year and beyond into the new stadium.
"For not a lot of money, compared to what other teams are spending, Mauricio Pochettino has done a wonderful job."
