Jose Mourinho named two Tottenham players that could help them challenge for the Premier League title earlier in the season.
The Portuguese has been out of work since he was sacked by Manchester United last December, but it now eager to get back among the action.
In his role as a Sky Sports pundit, Mourinho was asked whether he was surprised by how Mauricio Pochettino struggled to secure positive results so far this season, and he named a reason for their recent failings.
He said: ”I always felt the biggest investment Tottenham could do is what they did in previous seasons – which was keeping their best players.
“Some clubs, they can do both, they can keep their best players and buy other top players.
“I think they showed clearly the group is fantastic with lots of young and English players.”
The former Chelsea and Manchester United boss went on to pick out two big reasons why Spurs can succeed, naming to members of their current playing squad.
“Of course, they were very close to making history,” he said about their recent Champions League final defeat.
“Once more, they kept their best players, brought in [Tanguy] Ndombele and [Giovani] Lo Celso.
“I thought they would be ready for that challenge [for the title].”
In the club’s official statement after his appointment, Mourinho mentioned the fans as one reason for his move, despite his connection with rivals Chelsea.
He said: “I am excited to be joining a Club with such a great heritage and such passionate supporters.
“The quality in both the squad and the academy excites me.
“Working with these players is what has attracted me.”
Chairman Daniel Levy added: “In Jose we have one of the most successful managers in football.
“He has a wealth of experience, can inspire teams and is a great tactician. He has won honours at every club he has coached.”
