Mauricio Pochettino looking for Tottenham youngsters he can trust in pre-season, says Harry Kane

Tottenham put their faith in youth again in Tuesday's defeat by Roma in the United States.

Hours before the match in New Jersey, the club’s chairman Daniel Levy mocked the “totally unsustainable” spending of Spurs’ Premier League rivals after Manchester City’s summer outlay passed the £200m mark. “We can produce our own players. We don’t have to spend £20m, £30m, £40m on a player,” Levy said.

Spurs are the only Premier League club yet to make a summer signing but manager Mauricio Pochettino reflected his chairman’s confidence in youth by starting Cameron Carter-Vickers, Joshua Onomah and Kyle Walker-Peters for the second time on the club’s US tour. The homegrown trio were replaced at half-time with Spurs trailing to Diego Perotti’s penalty, while youngsters Anthony Georgiou, Harry Winks and Tashan Oakley-Boothe also appeared as substitutes at the Red Bull Arena.

Winks halved the deficit with a tap-in after Cengiz Ünder had seized on Kevin Wimmer’s mistake to make it 2-0 and Vincent Janssen looked to have sent the match to penalties after he flicked home a stoppage-time equaliser. But Marco Tumminello bundled in seconds later.

Onomah and Walker-Peters were part of England’s U20 World Cup-winning squad last month, while Carter-Vickers, playing on home soil, has already been included in the full USA squad. Levy obviously had the trio in mind when he talked about producing more homegrown players to follow in Harry Kane’s footsteps.

“These are games that the gaffer is looking for who he can trust,” said Kane afterwards. “When I was a young lad, in these games you looked to take your chance. Whether they are ready or not is down to the gaffer, but he has always had the philosophy that if you’re good enough to play you will play.

“It’s about working hard and if they get that opportunity, they are ready to take it.”

Walker-Peters, Cater-Vickers and Onomah did not entirely convince that Levy can continue to ignore the transfer market, however.

Carter-Vickers, who was at fault for at least one of PSG’s goals in Spurs’ 4-2 win in Orlando, was unlucky to give away the penalty when a cross struck his arm but he did not look comfortable, while Walker-Peters and Onomah struggled to influence the match.

“He is so young and needs to learn a lot,” Pochettino said of Carter-Vickers, 19. “He is a player with potential, yes, but we’ll see what happens in the end.

“He is like Kyle Walker-Peters, Josh Onomah, and today Anthony Georgiou and Tashan. We are talking about players that are young and need time to settle in the first team.”
