Really well worked goal. Another wonderful strike from Son.
Lovely ball in and a flick around the corner from Perisic.
Keeper has no chance again. What a finish.
Preston 0-2 Spurs
Preston bring on ex-Oxford midfielder Ben Woodburn for ex-Oxford midfielder Ryan Ledson.
Son Heung-min
Spurs are surely in round five now. Ivan Perisic flicks the ball to Son Heung-min, who has his back to goal. The South Korean spins past Jordan Storey and hammers the ball into the back of the net.

Too many reserve player flops for Spurs, Bissouma has turned out to be another failed signing.

Spurs are getting three or four subs ready. Preston are planning at least one too.
FT: Bristol City 3-0 West Brom
Baggies boss Carlos Corberan told BBC WM 95.6: "We made more technical mistakes today than in other games and we suffered a lot of counter-attacks. I didn't see the mentality of my team out on the pitch today.
"It's a disappointing feeling to have lost tonight and to not keep going in the competition, which was of course the target that we had. We lost the ball more today in the middle of the pitch than normal and that gives the advantage to the opponent to attack you.
"We didn't manage the game well tactically but also when it came to the last pass, the last cross, the last part of the attack, we did not do it with the normal accuracy."
Preston 0-1 Spurs
Spurs have some control on proceedings again. Matt Doherty is inches away from reaching Yves Bissouma's inswinger.
Preston 0-1 Spurs
Preston are really making a game of this now. Good to see. It's always a major shame to just go out with a whimper.

Evans did really well. Holds Spurs off.
The pass to Whiteman, he can't get enough bend on it.
Great response though.

Benjamin Whiteman has a good Preston chance. He's picked out 20 yards out, cuts the ball onto his left foot and tries to curl it into the far corner. He doesn't get enough curl onto it though.

It was poorly played from Spurs but Cannon was expecting a touch and he dives.
The ref got that one right.
Preston 0-1 Spurs
Tottenham Hotspur have had 71.1% possession over the opening 15 minutes of the second half.
Preston 0-1 Spurs
Preston's Thomas Cannon tries to win a penalty - but gets booked for diving instead.
He tries to cut back in the box and I think he's expecting Japhet Tanganga to lunge in so throws himself to the ground. Sadly for him the defender didn't make any such move so it was a clear dive.
Preston 0-1 Spurs
Robbie Brady's corner is poor and headed away by Japhet Tanganga at the near post.
Preston 0-1 Spurs
Decent spell for Preston and the noise levels go up. Alan Browne wins the first corner of the game and the levels rise again.

Spurs are moving quicker now. The confidence from the goal will be fuelling them and that is what they got to do.
Preston 0-1 Spurs
Spurs have scored 34 second-half goals this season - and only 16 before the break.

Spurs have a corner, their seventh of the game. Preston are having to dig deep now. Dig deep at Deepdale.
