PENALTY - Liverpool
McCarthy denies Benteke! The Belgian beats Delaney to drift into the box but his shot is too close to the Palace goalkeeper.
Four minutes of added time to play at Selhurst Park.
Bolasie now comes over to the right in space but his ball into the box is a poor one that is cleared by the first man.
Moreno denied by the woodwork! Delaney halts Coutinho with a fine interception on the edge of the D but Moreno meets the follow up with a sweet left-footed strike that comes back off the inside of the far post. The ball is retrieves and flung back into the box for Coutinho, but he gets a scissor kick all wrong and misses the ball completely.
Sako takes it, but blasts it high and wide. Huge waste.
Moreno is the latest player to be booked after a challenge on Zaha out on the right wing.
Just under 10 minutes remain at Selhurst Park.
Here's a double change for Palace with Dwight Gaykle and Bacart Sako on for Joe Ledley and Adebayor.
Great chance for Benteke who has just come off the bench as Lovren's flick on falls to him at the near post, but he can't steer it past McCarthy.
Firmino steps across Bolasie in what looks like a clear foul with Palace on the attack, but the referee waves play on. Bizarre decision.
BREAKING: Chris Smalling returns at centre-half alongside Daley Blind while Fellaini takes a spot on the bench. Marcus Rashford continues up top but Memphis Depay drops to the bench.
Manchester United team to face West Brom: De Gea, Darmian, Smalling, Blind, Rojo, Carrick, Herrera, Lingard, Mata, Martial, Rashford.
Subs: Romero, Fosu-Mensah, Varela, Schneiderlin, Weir, Fellaini, Memphis.
Disaster for Alex McCarthy. He makes a mess of a simple back pass, slipping and drilling the ball straight at Firmino. He takes ball a couple of yards inside the penalty area and provides the cool finish, slotting past the Palace goalkeeper.

Firmino tries his luck from range but it is a fairly easy save for McCarthy.
Palace defend brilliantly again as Lallana threatens to jink through but Delaney keeps his eye on the ball and makes a vital interception.
