Everton reached the FA Cup quarter-finals after edging out Tottenham Hotspur in a nine-goal classic at Goodison Park.

A magnificent contest swung in both teams’ favour before Carlo Ancelotti’s hosts – showing huge reserves of resolve and fitness – finally struck the decisive blow when Bernard fired home in the seventh minute of extra time.

Spurs dominated the early exchanges and were rewarded when Davinson Sanchez headed in from a corner in the third minute before Everton sprang to life with a three-goal burst inside eight minutes before half-time.

Dominic Calvert-Lewin, who later went off with what looked like a groin injury, levelled nine minutes before the break with a shot Spurs goalkeeper Hugo Lloris should have saved, before Richarlison’s fine low drive and Gylfi Sigurdsson’s penalty looked to have put Everton in command.

But Erik Lamela scored in the closing seconds of the first half to put Spurs back in contention and Sanchez pounced again after more chaos at a corner to drag Jose Mourinho’s side level just before the hour.

Mourinho then introduced Harry Kane but it was Everton who edged ahead again as more brilliant individual work by Richarlison restored their advantage after 68 minutes – but it was inevitable Spurs’ main man would have a say.

It came with seven minutes of normal time left as Everton were undone by the old firm, Son Heung-min’s cross the perfect invitation for Kane to score with a far-post header.

All the momentum appeared to be with Spurs but Everton are now a side to be reckoned with under Ancelotti and Bernard cashed in after more good work by Sigurdsson – who was involved in three goals – to beat Lloris with an angled finish.

There was still time for Spurs to respond but Everton saw out an outstanding victory in relative comfort.

Kyle Walker, Raheem Sterling and Gabriel Jesus were on target as Guardiola’s team won a 15th game in a row in all competitions, with Swansea pulling one back late on through debutant Morgan Whittaker.

This triumph means Manchester City have set a new record for successive domestic wins by an English top-flight club, surpassing the previous best of 14 achieved by the Preston team of 1891-92 and the 1987-88 Arsenal side.

Kelechi Iheanacho scored a 94th-minute winner as Leicester edged past Brighton to reach the FA Cup quarter-finals.

Substitute Iheanacho nodded in from Youri Tielemans’ cross to settle an otherwise unremarkable contest.

With both sides making seven changes for the tie, the first half was a slow burner and neither team were able to register a single shot on target.

The second half improved slightly with Andi Zeqiri and Cengiz Under both having efforts ruled out for offside.

The quarter-final draw takes place on Thursday, with matches being played across the weekend of 20-21 March.

Billy Sharp’s penalty sent Sheffield United into the FA Cup quarter-finals at the expense of 10-man Championship side Bristol City.

The game’s defining moment came when David McGoldrick’s goal-bound shot hit defender Alfie Mawson on the hand.

After viewing replays on the video screen, referee Robert Jones sent off Mawson and awarded the Blades a penalty, which Sharp slammed home.
