Just one game, against Fulham in 10 days' time, separates Tottenham from a semi-final, just three from a ninth FA Cup win. Bolton, meanwhile, had almost acquiesced to defeat before they stepped on to the pitch. Manager Owen Coyle had made his priorities clear by resting first-team regulars Kevin Davies and Johan Elmander, but he would still have been disappointed by the ease with which Tottenham demolished them.
The home side, crucially, scored early. Luka Modric, enjoying some rare space on the left, released Pavlyuchenko. The Russian was a little fortuitous that the ball broke for him, as he tried to spin past Zat Knight, but his finish, left-footed from 14 yards, was immaculate.
It was no more than Tottenham deserved for a dominant start. The tricky David Bentley jinked up and down the right wing, the leonine Jermain Defoe prowled along the edge Bolton's area.
Before long they were two ahead, and it was goalkeeper Jussi Jaaskelainen who presented them with their goal. Bentley cut the corner back to Tom Huddlestone, who shaped to shoot but instead slipped the ball right for Wilson Palacios.
Jaaskelainen misjudged the cross horribly, the ball ricocheting off the Finn's right knee and in.
Game plan in tatters, Bolton advanced. Ivan Klasnic had already given the hosts a scare by unwinding a shot from distance after Gareth Bale had swung at, and missed, an attempted clearance, and he went close again shortly before half-time. Fabrice Muamba played the Croatian through, but the shot from an angle was well saved by goalkeeper Heurelho Gomes.
Eidur Gudjohnsen came on for Defoe at half-time, and his first act on the pitch contributed to the third goal. The Icelandic striker controlled the ball on the left and slipped the ball through for Bale, whose cross was turned in by Andy O'Brien for another own goal.
Substitute Mustapha Riga forced Gomes into another fine save with a header from close range. But Tottenham were always comfortable, and in Danny Rose, brought on as a late substitute, appear to have a potential replacement for Aaron Lennon on their hands.
The former Leeds winger's break burst down the right crowned the evening for Tottenham, crossing for Pavlyuchenko to score a late fourth.
