Southampton 1-0 Norwich
A goal befitting of the game, as Shane Long sends Saints into the fourth round...
Southampton 1-0 Norwich
Norwich didn't have a shot on target in the 90 minutes and had 37% of possession. The Canaries have won three games since mid October.
A reminder of who awaits in the fourth round.
Newcastle will travel to face League One side Oxford.
Liverpool will host Wolves in an early kick-off, and Southampton host Arsenal in another televised game.

A brave, brave fight from Plymouth and they can be proud of how they performed on both occasions.
They have made a lot of money from the FA Cup and maybe Derek Adams will be able to spend that as they try to go up.
Jurgen Klopp was also brave in picking so many young players but it is Liverpool who go through.
Plymouth Argyle 0-1 Liverpool
The home crowd give their side a heroic reception at full time, as each man is clapped to the rafters as they come off the field.
Argyle will have made around £1m from these two games. In League Two terms, that's massive.

Plymouth have had a real go so full credit to them. They have just not found that bit of quality in the final third to score against Liverpool and that is what has done them.

Ash: Where's James Milner when you need him? A good English penalty taker, if you can believe that.
Jack Richardson: It's good to see we've given this a right old go, even if we go out, well done everyone out there, for all of the 180 mins #pafc, external
Shane Long (90+2 mins)
A scruffy, scruffy goal to settle an ugly match but one that Southampton deserve. They have pummeled Norwich in the second half, albeit without landing many shots.
An almighty scramble sees Shane Long get to a loose ball just in front of the kitchen sink to scuff it over the line from a yard out.

Ex-Leicester striker on BBC Radio 5 Live Sports Extra
Southampton are looking likely to score now. They had an awful lot of possession up to the 80th minute and never in a million you saw them getting something . Now there is a chance of them winning this.
