​Former Everton player and current BBC pundit Phil Neville believes Tottenham Hotspur's English striker Harry Kane would someday need to leave Spurs in order to realise and fulfill his true potential.

Spurs defeated Borussia Dortmund at Wembley and Kane proved yet again that he has the potential to become a world beater. Although Neville reckons that could only be achieved once he moves to a team that never ceases to win trophies.

Speaking to BBC, Neville said, "He(Kane) could have to leave Spurs to become that real top, top, world class, Lewandowski type player."

Neville also believes that if Spurs do not win a Premier League title soon, Kane will look out for other opportunities as he continued, "If Spurs maintain being just a top four team, that will not be good enough for somebody like Harry Kane. I think he needs to be challenging for Ballon d’Ors, I think he needs to be challenging for Champions Leagues."

Neville says that there will always be a doubt over Kane's ability until he joins a big club the same way Robert Lewandowski did when he joined Bayern from Dortmund. 

He concluded by saying, "When he [Lewandowski] went to Bayern Munich and proved for one of the biggest clubs in world football, people started to then think ‘Lewandowski is world class."
