Leicester City's hopes of securing a Champions League place have suffered a further blow away to Everton.
Brendan Rodgers' side fell to a 2-1 defeat at Goodison Park.
It took just 10-minutes for Everton to break the deadlock.
Lucas Digne and teenager Anthony Gordon combined down the left. The ball was squared to Richarlison who fired low and true past Kasper Schmeichel.
Six minutes later it was 2-0. Digne was involved again, floating in a free-kick of the head of Michael Keane which was met instead by the hand of Wilfred Ndidi.
Following consultation with VAR, the penalty was given and dispatched by Gylfi Sigurdsson.
Leicester came out for the second half like a side that had been treated to some half-time fireworks from their manager.
The visitors were back in the game six-minutes into the second period. A Jamie Vardy flick inside the box wasn't dealt with, Kelechi Iheanacho latched onto the ball and found it bouncing off his person and past Jordan Pickford.
Despite some wobbly keeping from Pickford after that, Leicester couldn't find an equaliser.
Rodgers' Foxes remain without a win in their four games since the restart, and have lost their last two.
Arsenal 4 Norwich City 0
Norwich City are dead men walking in Premier League terms following a 4-0 pasting away to Arsenal.
There was a minute's silence prior to the game, and Arsenal players wore black armbands in honour of the club's former assistant manager Theo Foley who died last week.
One can only speculate how different things may have been for Norwich had Ben Godfrey's early long-range effort found the net instead of the woodwork.
After some dithering on the ball from Tim Krul, Pierre-Emerick Aubameyang pounced, dispossessing the keeper to give Arsenal the lead 12-minutes before the break.
Four minutes later the game was over as a contest. Aubameyang laid the ball off to Granit Xhaka who made it 2-0.
Midway through the second half Aubameyang made it 3-0, capitalising on another calamitous ball across the edge of the Norwich box.
And to add insult to injury, Cedric Soares made it 4-0 just before full-time.
Defeat leaves Norwich six-points from safety with six games to play.
Bournemouth 1 Newcastle 4
It was the Alain Saint-Maximin show at the Vitality where Newcastle's impressive run continued.
Steve Bruce's side scored 4 goals in a Premier League game for the first time since May 2019.
Saint-Maximin provided assists for three of those, most dazzlingly for Sean Longstaff's 30th minute goal to make it 2-0.
Dwight Gayle, Miguel Almiron and Valentino Lozaro all found the net in a 4-1 win at Bournemouth.
Defeat for Eddie Howe's side means they dip below Aston Villa to 19th in the table.
