Kane, 28, has endured a difficult start to the season for Spurs, with one goal in ten Premier League appearances following his failed summer move to Manchester City. But he has scored seven goals in two games for England this past week.
Keane said, "Conte will be delighted [with Kane's goals for England over the international break].
"A lot of managers complain about their players playing for their country - I've experienced that myself - but Conte will be sitting at home going, 'what he's doing with England is better than any training he could've done'.
"He's scoring goals, he'll go back to Tottenham with spring in his step."
