The striker headed to the European Championships with the England U21s and has so far struggled to make an impact this season.
The striker continued his goal drought as he once again failed to score against Sunderland, only managing to get one of his four shots on target at the Stadium of Light. In contrast, Barkley was in fine form again in his side’s 3-1 win over Chelsea, as he assisted two of Steven Naismith’s goals to take him to three assists and two goals in five games.
There was a big debate about whether he and several others should have headed to the European Championships this summer, with Everton standing firm that they wanted their young starlet to rest following a busy two years.
He wasn’t chose and that rest in the summer has clearly played it’s part in his fine start to the campaign. On the opposite end of the scale sits Kane, who played for the Under 21s this summer and has returned looking rusty.
And, while he insists that his fitness is not an issue, there is definitely something missing as he struggles for Tottenham Hotspur and the suggestions of burnout continue to rumble on.
With Barkley playing so well, could Kane have taken a similar stance to Everton and Barkley and avoided international duty this summer?
Kane would have profited more from an extended break over the summer than the failed international experience with he ended up receiving if his current form is anything to by. The faults don't all lie with the 22-year-old, naturally. The Tottenham striker is being marked far more heavily and has so far received little in the way of service.
Yet things could still be very different, with the rest having done him the world of good and leaving him fully fit for the beginning of the season.
Although it's a slightly different case, Everton's Barkley shows the route Spurs could have taken.
