Wilfried Zaha continues to be well marshalled down the left but is able to win a corner for Palace.

Palace swinging the ball around but without much incisiveness. Norwich continue to defend well.

Norwich come agonisingly close to a vital second.

The corner is flicked on by Kenny McLean and Mario Vrancic can't quite wrap his leg around the ball enough to turn it in at the back post.

More promising for Norwich.

Sam Byram and Teemu Pukki link up and the ball is slid in to Todd Cantwell, who can't get a shot off.

The ball is laid back to Alex Tettey, whose firm strike deflects out for a corner.

Palace make their second change - striker Connor Wickham on for midfielder Max Meyer.

James McCarthy fells Teemu Pukki. Got the ball but plenty of the man too.

Norwich may be retreating too deep now. A roar from the home crowd for their side to get forward but Palace remain on the ball for the most part.

Emiliano Buendia and Mario Vrancic over it...

The right-footed Buendia takes and swings in a brilliant effort that Palace keeper Vicente Guaita matches by diving to his right and tipping it round the post.

Norwich can't fashion anything from the resulting corner.

Emiliano Buendia slips it to Mario Vrancic, who clips it away from Max Meyer and is brought down by the German.

A free-kick almost straight in front of the net and just outside the area for Norwich.

Better, if still not great as Palace can only win the second ball and Cheikhou Kouyate, who replaced Mamadou Sakho at half-time, sees his cross deflected out for a throw.

Norwich eventually clear.

Another free-kick in a decent spot for Palace.

Can Luka Milivojevic do better this time?

Woeful. Luka Milivojevic batters the free-kick well over the crossbar.

Jordan Ayew takes a tumble under a challenge by Emiliano Buendia.

Buendia reckons Ayew has dived but there was contact.

Referee Jon Moss signals a free-kick. In a dangerous area on the left of the Norwich area.

Palace get the second half under way.

A fist bump for the linesmen and out come the teams for the second half.

Palace have been in Norwich's third more but the hosts have done more with the ball in the visitors' penalty area.

Norwich's attackers are doing a fine job of tracking back so far.

The hosts need to be careful not to sit too deep but have looked plenty bright on the counter in that first half.

Work to do for Palace.

Norwich doing a fine job of breaking up whatever Palace throw at them after that early Todd Cantwell goal.

They'd really wish they had a second going in to the break though after a couple of decent chances to end the half.

Norwich really need these to go in.

Another nice move from the Canaries sees Max Aarons picked out in space 10 yards out on the right of the Palace area.

The right-back snatches his effort wide of the left-hand post though.

Mamadou Sakho makes another error as he fails to connect with a long ball forward and it drops to Teemu Pukki.

The Finland international is one-on-one with James Tomkins, who does really well to shepherd Pukki out to the left and get in a block on an eventually tame effort.

Vicente Guaita gathers.
