Harry Kane's "head is not in the right place" at Tottenham, according to Dimitar Berbatov, who has urged the striker to take up the chance to join Manchester United this summer.
Kane has proven himself as one of the most prolific marksmen in European football over the past six seasons, scoring 181 goals in 278 outings across all competitions for Spurs.
The 26-year-old has earned two Premier League Golden Boots during that period, and played in a Champions League final, but has yet to pick up the first major trophy of his career.
