Poor.

Meanwhile, the £30m man Moussa Sissoko (Newcastle were laughing all the way to the bank with that one) comes off as Georges-Kevin N'Koudou enters the action.
Gent 1-0 Tottenham
From the resulting corner, Danijel Milicevic heads over the bar at the back post.
The Bosnian was unmarked and all on his own.
Gent 1-0 Tottenham
Spurs are all over the place.
Kenneth Saief makes a mug of Eric Dier down the leg before feeding skipper Nana Asare in the box.
The Gent man is in two minds whether to cross or shoot.
He opts for the latter which is headed away for a corner by Toby Alderweireld.

Son Heung-min is the man called to rescue the tie as he comes on in place of Mousa Dembele.

Gent 1-0 Tottenham
Eric Dier's free-kick is very poor, strangling it wide of goal.
Spurs need to pick themselves up, and quick.
Gent 1-0 Tottenham
Now then.
A Spurs free-kick in a promising position.
Dead centre, 30 yards out with Eric Dier over it...
Gent 1-0 Tottenham

Bradley Allen
Ex-QPR striker at Ghelamco Arena for BBC Radio London
Well that's really lifted the crowd because Spurs have had the better of it in the second half. It's one of Gent's few attacks.
That one little moment got beyond Dier and Perbet got the better of him and got the goal.
Spurs are up against it again and the home fans are really in the mood now.
Jeremy Perbet (59 mins)
The stadium erupts.
It is all too easy for Gent, who grab the lead.
Captain Nana Asare is allowed to drift into the box unchallenged and then has the composure to feed Danijel Milicevic.
The Bosnian keeps his cool to play it into Jeremy Perbet, whose first shot is blocked by Ben Davies, before falling nicely back into his path for the Frenchman to stroke him.
Spurs are stunned.
Gent 0-0 Tottenham
The pitch is not big enough for Dele Alli on this occasion.
Kyle Walker does brilliant to beat a man an find his team-mate in the box.
Alli's superb turn puts Brecht Dejaegere on the deck and as he tries to get a cross away, it rolls out of play.
Gent 0-0 Tottenham
A rash challenge from Kyle Walker which earns him a yellow card.
The ball is loose and there to be won, as the Englishman jumps in to get his foot on it first, before catching Kenneth Saief on the follow through.
Did he have full control of his body? It could easily have been a red card.
Gent 0-0 Tottenham
Aaah, just didn't catch it well.
Gent forward Danijel Milicevic has an opportunity to put his name at the top of the sports websites, but lashes a shot wide as the ball bounced up to him inside the area.
He should have done better. Hugo Lloris is not happy with his defenders.
Gent 0-0 Tottenham
Spurs are pushing Gent higher and could soon get the first goal.
Home defender Thomas Foket makes a mess of clearing Harry Winks's cross, allowing Harry Kane to tee up Mousa Dembele, but the Belgian screws his effort wide of goal.
Gent 0-0 Tottenham
Spurs have started well in this second half and are inches away from the opener.
Impressive midfielder Harry Winks tries to play the ball on the inside of the Gent left-back, which Kyle Walker sticks out a leg to get on the end of.
The ball gets to Dele Alli inside the area, who goes down under a challenge and it breaks to Harry Kane.
With two defenders around him, the English striker spins and shoots with his left foot, but the balls ricochets off the outside of the post.
Should he have done better? Probably should.
Gent 0-0 Tottenham
Back off and running in the second half.

BBC Radio London's Andy Rowley at Ghelamco Arena: "Gent have definitely done their homework and are causing Spurs some problems.
"The Tottenham fans are well represented tonight and will want to see an improvement.
"This is of course the birthplace of Bradley Wiggins, so Spurs need to get on their bike in the second half."
