Tottenham chairman Daniel Levy has no plans to ever sell another player to a Manchester club.

With Manchester United pursuing Harry Kane, it's emerged Levy still regrets selling Kyle Walker to Manchester City.

The Daily Mail says Levy agreed to the £45m sale of the England right-back to City. Over the past six years, Walker has proved himself among the best right-backs in the world.

Levy has never forgiven himself for letting it happen and has vowed never to make the same mistake again.

This could prove a problem for United - and Kane, who is keen to explore a summer move to Old Trafford.

Kane's contract expires at the end of next season so Spurs will be very aware that this could be their final chance to cash in.
