Joshua Zirkzee says "hard times create strong people" as the summer signing looks to put a difficult start to life at Manchester United behind him.

The 23-year-old became the first signing of the Ineos era and initially hit the ground running after his 42.5m euros (£35.7m) summer switch from Serie A side Bologna.

Zirkzee scored the winner in United's season opener against Fulham but failed to register another goal under Erik ten Hag, who paid the price for the club's poor start to the campaign in late October.

Ruben Amorim was swiftly named successor and Zirkzee marked his first start under the Portuguese head coach with a brace in Sunday's impressive 4-0 win against Everton at Old Trafford.

"Great day," Zirkzee said after his first goals since August.

"A good win on a Sunday is exactly what these fans deserved, so it's a great day.

"There were a couple of moments where it could've gone differently but I think we stayed strong as a team and 4-0 is a great result at the end of the day.

"Hard times create strong people and strong people bond. I think that's what's happening now."
