I think this takes a deflection. The keeper had no chance.

Luton deserve this, but Cambridge will be so frustrated having had so many chances.

Luton make a double change to throw on some fresh legs for the final few minutes.

Cambridge are going long with time against them but you feel this Luton defence will clean up these high balls into the box all day long.

It’s five changes for Tottenham from the side that lost 2-0 to Chelsea 13 days ago.

Emerson Royal, Cristian Romero, Ben Davies, Sergio Reguilon and Lucas Moura all come in.

January signings Rodrigo Bentancur and Dejan Kulusevski are both on the bench.

Tottenham XI: Lloris, Royal, Romero, Sanchez, Davies, Reguilon, Winks, Hojberg, Lucas, Son, Kane.

Brighton captain Lewis Dunk starts for the first time since December 1 after recovering from a knee injury. He is one of five changes from the team that drew 1-1 with Leicester last time out on January 23.

Tariq Lamptey, Yves Bissouma, Adam Lallana and Solly March are also all given starts after missing out.

Brighton XI: Sanchez, Lamptey, Cucurella, Webster, Dunk, Bissouma, Maupay, Gross, Lallana, Moder, March.

Jed Steer is almost caught out by a ball into the box, he pushes it away and the Luton defence clears before Lorent Tolaj can pounce.

Luton make another change as Harry Cornick - who has eight goals this season- replaces veteran Cameron Jerome in attack.

Cambridge are upping the pressure with Luton struggling to get out of their area but there's relief for the visitors as the home side's momentum is halted as the whistle goes for a foul inside the box.

It is a triple change for Cambridge as Adam May, James Brophy and Harvey Knibbs are replaced by Ben Worman, Jack Lankester and Lorent Tolaj.

Cambridge are on the attack but they can't find a way through the Luton defence as James Brophy sees his shot blocked.

There's a couple of changes about to be made by the home side.

Luton make the first change of the game as Elliot Thorpe, after taking a few knocks in this game, is replaced by Danny Hylton.

The forward has history with Cambridge, having scored six goals against them including a hat-trick in a 7-0 win back in 2017.

Wes Hoolahan's shot from the edge of the area is blocked as Cambridge attack. They need to get a goal soon if they are to have a chance of getting back into this.

Elliot Thorpe just wants to keep playing. After a bit of treatment he is back on and good to go.

Elliot Thorpe is down injured again after a clash. This might be a knock too far and Luton boss Nathan Jones sends a couple of his players out to warm up.

... but the delivery from the set piece is over everyone. The wind is making things really unpredictable.

Admiral Muskwe charges forward for Luton. It looks like he loses out in a battle with two Cambridge players but does manage to win a corner...

Huge chance for Cambridge United to get back into this!

It is route one as James Brophy knocks a long ball down into Sam Smith's path but the striker hooks his effort wide.

He had to get it on target at least.

Wes Hoolahan goes low with this free kick but it is comfortably cleared by Cameron Jerome.

A wasted opportunity.
