Harry Kane fears the financial restrictions of Tottenham's new stadium will make it tough for Mauricio Pochettino to keep improving the team and target the trophies he is determined to win.

England captain Kane will be 26 in July and has made no secret of his desire to start adding medals to his goal records and individual accolades.

Tottenham have recorded three straight top-three finishes under Pochettino but, without silverware since 2008, are experiencing their longest trophy drought since the Second World War.

'A lot of people say this is maybe the best team we've had, maybe the best team we'll ever have, and the best manager, but it's important we have something to show for it,' said Kane in an interview with ESPN.

'It's not just when we look back in 10 years, we had a great team. It's, "Look what they did. Look what they won".

'The challenge for us is, can we keep going up and up and up? It's going to be difficult in the next couple of years with the stadium and the finances.

'We've done so much in a short space of time. Of course we want to go on to the next level, win the Premier League and win trophies.'

Kane signed a six-year contract at Spurs last summer and is not agitating for a transfer, despite interest from Real Madrid, but he has clear ideas of where his career might progress.

He is serious about moving on if Spurs stagnate as they pay for their new home, expected to cost more than £1billion.

Tottenham's final test event for the stadium at White Hart Lane is a legends game against Inter Milan on Saturday, before the official opening against Crystal Palace in the Premier League on Wednesday.

It will also host American football, with the club keen to promote the new venue as the London HQ for the NFL, and Kane intends to try his hand at being a kicker for an American football team at the end of his sporting career.

'That's real, something that in 10 or 12 years I definitely want to try,' said Kane, an avid fan of the NFL and someone who cites Tom Brady as his hero because the New England Patriots quarterback inspired him to overcome setbacks early in his career and reach the top.

'We've had a similar path, being doubted when we were younger, maybe not being the best athletes as kids,' he said.

'It was quite a big inspiration. Not many people thought he'd become that good, or even play in the NFL, and he went on to become the best ever.

'At the time, it gave me a real boost to say, "Look, anything is possible". If you have that self-belief and that drive and that hunger, you can do it.

'It goes back to that drive to be the best.

'If you play in the Premier League and the World Cup and you then play in the NFL, would you then be considered one of the greatest sportsmen ever?'
