Arnaut Danjuma
Arnaut Danjuma scores on his Spurs debut!
The Villarreal loanee is unmarked 10 yards out to send Dejan Kulusevski's low ball into the bottom corner.
He scuffs it a bit but they all count.

Player of the match for me is Son. Has to be.
Tried so hard in the first half then tried again in the second half.
Two great strikes and Preston have made it hard so you need that bit of brilliance and Son has provided that.

Son Heung-min looks in real pain on the bench. Not sure what's up there, he's not having any treatment or anything. Maybe he's just really tired.

Son doesn't suddenly look good again because Kane isn't playing. It's because he is playing against a team that are obviously not at the same level as him.

Son Heung-min, the official man of the match, is replaced by Bryan Gil.

Ivan Perisic crosses for Spurs but it's caught by Freddie Woodman, whose father once wrote a book with Gareth Southgate.

The word on the street is that Son Heung-min is coming off. Alan Shearer says he wouldn't be happy about being replaced while he was chasing a hat-trick.
Harry Kane isn't the man coming on.
Preston 0-2 Spurs
Spurs had Harry Kane on the bench today in case of emergency. The striker has been ill this week though.
So I bet they're relieved they don't need to call on him.

Corner to Preston. Can Alan Browne make this one count? They need to score soon if they're to have a chance.
The corner isn't bad but Fraser Forster catches it.

When Son plays like this without Kane you wonder if maybe Tottenham should cash in on Kane in the summer?!

Just when you need a bit of magic after a slow start, Son comes out with those goals.
He has twice now in the second half. Could be on a hat-trick.

Arnaut Danjuma is almost in with his first touch but it's just cut out by a Preston defender.
