The Tottenham Hotspur striker scored his first league goal of the season this weekend - at the seventh time of asking.
Spurs embarked on a tour of Asia and Australia in May before Kane joined up with England’s Under-21 side for the European Championship the following month.
The 22-year old has had scant time to rest as a result, and some have cited fatigue as a possible factor in his early-season form.
"It was great to see Harry score and the performances I have seen have certainly merited that reward,” said Glenn, in quotes published by the Evening Standard.
"A number of our young players are thriving in the league, having played in the summer Under-21 tournament, although they didn’t all embark on commercial tours of the Far East with their clubs, as Harry had to with Spurs.”
Tottenham’s post-season tour was criticised at the time - particularly for Kane’s involvement - but it provided a useful opportunity for the likes of Harry Winks and Josh Onomah to show their qualities in the first-team set-up.
Saturday’s emphatic 4-0 win over Manchester City brought about Kane’s first goal of the season, with his well-taken first-time finish giving Spurs a two-goal cushion, and it was a performance that showed no signs of fatigue.
Mauricio Pochettino will hope his talismanic striker can now kick on without the pressure of that ‘first goal’ looming over him, and with Spurs slowly hitting top gear – you wouldn’t bet against it.
