Harry Kane's goal in Tottenham's 1-0 win over Sunderland was just another reminder of how important a player he is for Mauricio Pochettino's side.
Spurs squandered a host of chances and should really have thrashed the Black Cats, but Kane was the only player to find the back of the net, once again showing his eye for goal.
The 23-year-old doesn't always get off to the best start when a new Premier League season dawns, though he's got off the mark far more quickly this time with goals against Stoke and Sunderland.

In fact, the overriding concern at Tottenham has not been his form, but the club's over-reliance on him. The fear has always been that should Kane get injured, Pochettino could find himself in a sticky situation.
That is exactly what has happened, with the striker having to be carried off the pitch in the second half. Fortunately, the England international had already made his mark with the winner, but if you're a Spurs fan, it doesn't get much worse than witnessing Kane struggling to walk.

After the game, the news only got worse, as the forward was pictured leaving White Hart Lane on crutches and wearing a protective boot by James Olley, a reporter for the London Evening Standard.
The same paper is also reporting that Mousa Dembele and Eric Dier - who both had to be taken off looking in some discomfort - only suffered cramps, but Kane's fitness will still be the main worry.
The Lilywhites star won't find out the extent of his injury until Monday, but he'll almost certainly miss the Gillingham game midweek, and probably Saturday's trip to Middlesbrough too.
Frustration for Spurs
Obviously, any knock of his will always lead to questions about Tottenham wearing him out, but as his ankle appeared to roll over, it's pretty clear fatigue can't be blamed for this one.
Even the summer signing of Vincent Janssen hasn't entirely appeased Spurs' lack of depth up front, with the Dutchman coming under fire for selfishly wasting a good chance near the end of the game.
What's most frustrating is that Kane's injury has come at a time when he looked like putting a run of goals together, so Spurs fans will be praying this doesn't set him back any further.
