Right then, that's about it from White Hart Lane - take a look at the match report if you want a reminder of how Spurs came back from a goal down to claim an emphatic victory.

Or, if you want more Premier League goals, then you can follow the rest of Saturday's top-flight action here.

Tottenham boss Mauricio Pochettino told BBC Sport: "It was a good response to the Leicester defeat. I’m very pleased. We need to be patient. 

"We had a lot of shots on target – their goalkeeper was fantastic. I feel very pleased in the last few games. The belief is fantastic. We have a very good, strong squad – today was a good example."

And here is Allardyce on 21-year-old Sunderland goalkeeper Jordan Pickford, who had a much more impressive Premier League debut, making several good saves despite conceding four goals.

Allardyce told BT Sport: “Jordan Pickford is a good lad. The experience he has gained on loan has helped him out a tremendous amount. He looks comfortable at this age. It’s a bright future for us and for him."

Sunderland boss Sam Allardyce was talking to BT Sport about Jan Kirchhoff's debut, which came when he brought him on as third centre-back just before the hour mark: “Our legs were running out and I wanted to make sure we had the energy to stay in the game. 

"John O’Shea and Wes Brown are in their late 30s so will feel the pace of the game. The extra defender was to tighten it up. 

“It’s coming in the Premier League for the first time. He’s found out how difficult it is. We had to get him on at some stage. You can’t judge a man on one swallow. He knows what the pace is like now. He’s contributed to the loss with the penalty. But we opened up too much – that was the problem."

I've just seen a few stats from White Hart Lane. Basically, Christian Eriksen wishes he could play Sunderland every week...

Eriksen has now scored in all four of his Premier League appearances against Sunderland (five goals).

The Dane has netted more goals against Sunderland in the Premier League than versus any other opponent (5).

Eriksen scored in the Premier League from open play for the first time in almost a year (Jan 17th 2015 the last time before today – also versus Sunderland).

Sunderland boss Sam Allardyce gets his metaphors a bit mixed up when he is asked about Jan Kirchhoff's less than illustrious debut.

Allardyce told BT Sport: "You cannot judge a man on one swallow."

No, this isn't Jan Kirchhoff talking about his Sunderland debut...

Black Cats keeper Jordan Pickford told BT Sport: “I found out this morning I’d play. I was buzzing but the result didn’t go our way. I’ve had a lot of experience in the lower leagues. I didn’t feel too nervous. 

"It’s nice to get an early save. Making your Premier League debut is a dream come true, a shame the result wasn’t the same. We’ve got a good week training ahead of us before Bournemouth next Saturday.”

Here's when Jan Kirchhoff's afternoon started to go wrong. The 59th minute, when he replaced Danny Graham. It was all going so well for the big German until then...

Spurs striker Harry Kane told BT Sport: "We were trying to play too much around their area instead of getting shots off [earlier on]. The second half was a solid performance. 

"Whenever you come off a defeat you have to bounce back and we’ve done that. It’s still a long way to go until May. We’ll just keep working hard."

Sunderland, needless to say, remain in the relegation zone after that second-half rout which ended their mini-revival. They are a point behind 17th-placed Swansea but their goal-difference took a bit of a pounding today, as did their defensive record - which was already the worst in the top flight.

Tottenham return to winning ways in emphatic style after that midweek slip against Leicester. They are four points off the top of the table - I wonder if Sam Allardyce thinks they have got the bottle to win the title now?

Andrew Priestley: Welcome to Premier League football Jan Kirchhoff! It's a whole different ball game here Jan! Like a fish out of water!

"Tottenham ran riot after Sunderland switched off. They gained complete control of the game and ran away with it in the second half."

Referee Mike Dean blows the final whistle to end Sunderland's misery. Black Cats goalkeeper Jordan Pickford did not deserve to lose 4-1 on his Premier League debut, but it is safe to say that their centre-back Jan Kirchoff did.

"I think a whole host of teams could still win the title, and this is a really big result for Tottenham. They responded so well today after falling behind, and this big win will heap pressure on the likes of Manchester City."

Tottenham have got three minutes of added time to find a fifth goal. They are camped outside the Sunderland area, looking menacing.

Tottenham are coming forward in search of more goals. Sunderland just want to get out of White Hart Lane as quickly as possible.

We are inside the last four minutes, and I think we can forget about a Sunderland comeback.

Tottenham are making their third and final change - Harry Kane departs to a standing ovation and on comes Son Heung-Min.

Ryan Nurse: From the sounds of things, Jan Kirchhoff is having the worse Premier League debut since Ali Dia.

Sunderland have conceded three goals since Kirkchoff came on as a substitute. One goal deflected off the German and he then conceded the penalty.

"It's been all Spurs in this second half, and Sunderland have simply crumbled. Whenever Tottenham have attacked they have created opportunities and they deserve to be 4-1 up."
