Manchester City's Erling Haaland scored five times as the FA Cup holders ran riot in a 6-2 rout of Luton in the fifth round on Tuesday.

Aided by Kevin De Bruyne's trio of assists, Haaland completed his treble inside the first 40 minutes at Kenilworth Road.

Jordan Clark struck twice to briefly reduce Luton's deficit to just 3-2.

But any Luton hopes of an incredible comeback were ruthlessly erased by Haaland as the Norway striker scored twice more after the interval to send City into the quarter-finals.

Mateo Kovacic netted to cap City's second six-goal haul this season after their 6-1 thrashing of Bournemouth in the Premier League in November.

Haaland now has 27 goals in all competitions this season, making a mockery of the critics who took a swipe at him after a misfiring display in a recent draw against Chelsea.

On his form since returning from a foot injury that sidelined him for two months, Haaland said: "I'm getting back to my best. Finally I'm feeling good."

Abdul Fatawu's stunning strike gave Championship leaders Leicester a surprise 1-0 win at Premier League side Bournemouth.

Leicester struck in the 105th minute when Fatawu collected Kelechi Iheanacho's pass on the edge of the area and curled into the top corner.

Newcastle survived a scare to beat second tier Blackburn 4-3 on penalties after a 1-1 draw at Ewood Park.

Anthony Gordon's 71st minute opener was cancelled by Blackburn's Sammie Szmodics eight minutes later, before Newcastle keeper Martin Dubravka emerged as the shoot-out hero with two saves. (AFP)
