Spurs have rejected a £100m bid from Manchester City, with chairman Daniel Levy holding out for a fee closer to £160m.
Kane was missing from the Spurs squad which drew 2-2 with Chelsea in a friendly game at Stamford Bridge on Wednesday.
Berbatov pushed through a £31m switch to Manchester United from Spurs at the start of the 2008/2009 season by missing two games but always availed himself for practice and is surprised by the stance the England captain has taken in an attempt to exit North London
“I was surprised. I don’t think it’s the right way. I never boycotted training, that’s the difference," the former Bulgaria international forward told The Sun.
“I didn’t play two games. It was difficult for me to admit but I found the power to say, ‘If I play, my mind will not be there, so I will be in the way of my team-mates doing their job’.
“But training is easy. It’s behind closed doors, most team-mates will understand you, and it will be easy to let go of some stress with banter and jokes.
“I hope Harry resumes training, then the difficult and interesting part comes - the games.
“If it’s going to happen, I think it will be the last day of the window. But I would love it to be resolved sooner, because I don’t want to see him boycotting games."
Tottenham will play their first Premier League game of the 2021/2022 season against Manchester City next week.
