Portsmouth 1-2 Bournemouth
David Pleat
Former Tottenham boss on BBC Radio 5 live

Crystal Palace 1-0 Stoke
One Premier League team is safely through to the fifth round. One isn't.
Stoke schmoozed the League Cup in their run to the semi-finals, but they aren't wooing its more attractive, cooler, bigger brother.
Nottingham Forest 0-1 Watford
Jason Mohammad
BBC Sport presenter on Final Score
"For people who say the FA Cup doesn't matter, check out Quique Sanchez Flores' reaction to Watford's goal on Match of the Day tonight. Absolutely brilliant."
Crystal Palace 1-0 Stoke
Stoke throwing the kitchen sink at Palace. And the fridge and the bin. Joselu prods wide just after Phil Bardsley's drilled shot was saved.
Nottm Forest 0-1 Watford
Dion Dublin
Final Score
"Any ball that is in the box when you are playing against Odion Ighalo, he will score. You just want the Forest defender to connect with his clearance but it scrapes under his studs and falls to the Watford striker."
Craig Jones
The very definition of a consolation goal for Bury as Craig Jones controls a cross at the far post and fires in.
Arsenal 2-1 Burnley
Andre Gray races clear of the Arsenal defence, Gabriel gives chase, a half chance.... bobbled wide.
We go into injury time. Four minutes.
West Brom 2-2 Peterborough
Dion Dublin
Final Score
"Peterborough have had a right go. They haven't been frightened. West Brom have created plenty of chances but they haven't put them away, and Peterborough's second goal was outstanding."
