The 24-year-old midfielder, who has just joined Lens, is a big fan of the current Tottenham boss.

With Tottenham currently impressing under the management of Mauricio Pochettino, a boss famed for helping talented young players break into elite football, it would be easy for Bostock, now 24, to regret leaving North London when he did.

But after completing a move to Lens this summer following a successful stint in the Belgian top flight, he is only happy for his former Spurs teammates, and grateful that is career is going in the right direction.
"Since I left a lot of Spurs fans have messaged me and been in touch to say that I should have been given more of an opportunity," Bostock told ITV Sport. "Hindsight is a wonderful thing, you never know what would have happened but I am happy by how my career is progressing and I’m enjoying my football.
"I am buzzing for my old team-mates Harry Kane, Ryan Mason and Andros Townsend, I didn’t play with Eric Dier, but to see how the core of the Tottenham team has become the core of the England team shows how if youth is given its opportunity, it thrives."
All four young players have won caps for England under Pochettino, and Bostock went on to express his appreciation of the current Tottenham boss, even though he never got the chance to work with him.
“I think Pochettino is an amazing appointment for Spurs for what he’s achieved, coming so close to winning the league, it bodes well for English football in the future.”
The midfielder was heralded as one of the best prospects of his generation when he broke Crystal Palace's record for youngest ever player, aged just 15. There were reports that everyone was chasing him, including Barcelona in the Mail, so it was seen as something of a coup when Spurs were the ones that signed him, and then went on to make him their youngest player ever as well.
But a series of loans and very little first team football in North London saw Bostock slip from the limelight, and he left the club once his contact had expired in 2013 to take his career to Europe, first impressing in Belgium.
After scoring 20 times in two seasons for Leuven, he will now try his hand in French football with Lens, and even though his new side are in Ligue 2, it may not be long until Bostock is back in the top tier and being linked with a return to the Premier League as a first team player.
