Ben Davies scored his first goal for Tottenham as the eight-time winners ground out an FA Cup third-round win over a stubborn Aston Villa side.
After a dreadful first-half showing, Spurs improved and the Wales left-back found the breakthrough against their Championship opponents with a deft header.
Son Heung-min then wrapped up the victory when he converted Moussa Sissoko’s pass to put Mauricio Pochettino’s side in Monday’s fourth-round draw.
Tottenham have moved into third place in the Premier League on the back of a five-match winning run, but their second string struggled to click against a Villa side set out to frustrate.
Without the rested Dele Alli, Harry Kane and Christian Eriksen, the hosts were short of ideas and the tie looked destined for a replay until unlikely goalscorer Davies arrived inside the penalty area.
Villa mustered one shot on target all game and Steve Bruce will now turn his attention to overhauling a seven-point gap to the Championship play-off places.
Tottenham were excellent in beating Premier League leaders Chelsea 2-0 in midweek but, perhaps unsurprisingly, were nowhere near that level in the opening hour.
Of the XI who started against Chelsea, only Toby Alderweireld and Eric Dier kept their places – and it showed.
Alli, Kane and Eriksen had contributed 30 of Spurs‘ 51 goals this season, and 11 of 33 assists, before kick-off and without them Pochettino’s side looked toothless.
Stand-in striker Vincent Janssen, who has scored just three penalties in 23 appearances now, was particularly lightweight and it was only when Alli finally replaced him after an hour that Tottenham found a way through.
It was another replacement, Georges-Kevin Nkoudou, who crossed for Davies to head home before Son – who had moved up front once Janssen went off – buried the second.
A top-four finish remains Pochettino’s most pressing assignment but, after a dismal Champions League campaign, a first FA Cup win since 1991 is also surely high on his list.
Villa were beaten FA Cup finalists in 2015 and Bruce took Hull to Wembley a year earlier, but a repeat never looked likely as the visitors effectively played with a back six for large periods.
With top goalscorer Jonathan Kodjia away on international duty at the Africa Cup of Nations with Ivory Coast, they posed little threat and their only real chance came when James Chester and then Gabriel Agbonlahor had shots blocked from the same free-kick.
A return to league duty now awaits. Villa were 19th when Bruce took charge in October, but after just three defeats in 14 games since they could challenge for a place in the play-offs.
Tottenham manager Mauricio Pochettino: „It’s always difficult in the FA Cup, but we played a team that had very good organisation and it was tough to break them. We had lots of possession and a lot of patience to try and build from the back.
„At 0-0 we changed the system a bit to try and change the game and from that we scored.
„I’m pleased for the players that haven’t played too much, it’s important for them to build their confidence. “
Aston Villa manager Steve Bruce: „We had to defend well and run a million miles because they are a very good side. We had a big chance in the game.
„I was a touch disappointed with the goal because they didn’t have to do much – one cross into the box and we didn’t deal with it.
„You need your goalkeeper to play well and Sam Johnstone looks a very good young goalkeeper – I think he’ll relish the challenge to play week in, week out.
„They are a very good side and that has to be the aspiration for us at Aston Villa. “

This year Tottenham have taken Manchester City to the cleaners, beaten Chelsea and were the better team against Manchester United for 60 minutes.
A trophy is the obvious thing they are missing. The big thing Mauricio Pochettino has changed is the mentality. It’s about delivering it now.

Vincent Janssen is making life far too easy for defenders. He keeps coming towards the ball instead of getting into the six-yard box where he could actually score goals.
He is taking the easy way out and he looks to me that he is frightened of missing chances.
Unless he starts getting into the right areas, he is not going to score goals.
