Welcome to LIVE coverage of Everton v Chelsea in the FA Cup fourth round at Goodison Park!

Cole trips Coleman needlessly on the Everton right, and this will be a good set-piece opportunity for the home team.

Lovely football from Everton to win the ball in midfield and work it to the left side...

The corner comes to nothing, but Everton look marginally the likelier side to break the deadlock.

Chance for Saha! Rodwell clips a cross over from the right to the far post, but Saha's volley from a tight angle is blocked!

Coleman uses his hands to block a Terry clearance, then Terry uses his hands to bash the Irishman in the face accidentally on purpose.

On the Chelsea bench, John Obi Mikel is wearing a snood - nothing unusual there, except Mikel has got it over his mouth and nose...

Essien looks for Ashley Cole on the Chelsea left, but overhits his pass which goes out for a goal kick.

Baines sends in a good outswinging delivery, but there is no serious aerial challenge and Cech plucks it out of the air.

Second half under way! And immediately Everton have a corner.

Chelsea are late coming out, leaving Everton strolling about in the cold. You imagine Carlo Ancelotti is above that sort of chicanery, so we'll put that down to an honest mistake.

That's half-time, and still goalless in an even contest. Back in a few minutes...

Ouch. Seamus Coleman is hit flush in the head by a Didier Drogba free-kick. Good block, but his ears will be ringing in the morning.

One minute of added time to be played at the end of the first half.

Arteta has been quiet so far, but he goes for goal from 30 yards... drives it a couple of feet wide of Cech's goal, though it would have had to be an absolute thunderbolt to go in from there.

Anelka plays a lovely one-two and has space going into the box, but his cross is deflected into the hands of Howard.

Fellaini shapes to shoot, and Essien is across very quickly to charge him down. Alert play from the Ghanaian.

Everton release Saha through the middle, but there are four Chelsea defenders back and the striker has no support. No chance.

Baines surges down the Everton left, but halts and the Toffees contrive to play the ball all the way back into their own half.

Terry looks like he is climbing all over Saha, but the Frenchman is penalised for backing in... a 50-50 decision, that.

That flurry of activity around the half-hour mark has subsided, and the game remains very evenly balanced.
