Phil McNulty
BBC Sport chief football writer at St. Mary's
Really good first 45 minutes here and both team will fancy their chances in the second half.
Spurs have shown real pace and threat without finding the finishing touches but Saintas are also right in this.
All to play for as we clearly have two teams and two managers taking the FA Cup very seriously.

Josh Verrills: West Ham have created absolutely nothing in the first half of a home FA Cup tie against Championship opposition. No urgency or enthusiasm whatsoever. Hard to tell which side are the PL side and which are The Championship side so far
Good to see premier league standard football at London Stadium. Sadly, not West Ham playing it!

Oxford fans applaud their players off at half-time. They’ve held their own with Newcastle’s quality only shining through on a handful of occasions.
The biggest cheer of the first half was for a Newcastle fan heading a stray ball back onto the pitch in injury time.
If the second half is like the first, Newcastle face a second replay against lower league opposition in a row.
HT: West Ham 0-1 West Brom
West Ham are lucky to still be in this. They have been poor. Charlie Austin has made several big chances for the visitors.
HT: Southampton 0-0 Tottenham

Coventry City 0-0 Birmingham
Neil Johnston
BBC Sport at St Andrew's
I'd be lying if I said that was an enthralling first half. There was more entertainment off the pitch as both sets of fans traded good natured chants.
We're 45 minutes from a replay. If that happens then Birmingham will definitely be the home side.

Andrew Duffy: So, goal of the season to Son, save of the season to Tanganga?
James Burke: I think Birmingham are playing for a draw so they take Coventry back to St Andrews.

Tony Pulis
Former Stoke and West Brom manager on BBC Radio 5 Live
It's livened up. The first 15 minutes were pretty tepid. It's become more open, I think Tottenham look very, very dangerous on the break, they've had three or four great opportunities to get end products and haven't managed it - and Southampton are going to be a threat. Tottenham are narrow and they're leaving that space out wide. I've enjoyed the game.
As it stands we're on for six replays...
Southampton 0-0 Tottenham
Newcastle 0-0 Oxford
Portsmouth 2-0 Barnsley
Pompey in the lead.
Reading 1-1 Cardiff
All square.
HT: Millwall 0-0 Sheffield United
Paul Mortimer
Former Charlton player on BBC Radio 5 Live Sports Extra
It's still 0-0 but Sheffield United will expect their quality to come through and win them this game. Millwall have got to do more.
Coventry 0-0 Birmingham
Millwall 0-0 Sheffield United
Dire.
West Ham 0-1 West Brom
Boos at half-time at the London Stadium. West Ham have been so poor. West Brom should have a strong lead - they have missed some big chances.
Burnley 0-0 Norwich
A very good 0-0 so far.
John Marquis
Ronan Curtis nods it in from the corner but John Marquis gets the final touch on the line. They squabble over it while laughing back to the halfway line.
West Ham 0-1 West Brom
