"We were playing well, but we missed that bit of luck. We have to continue, there are still many matches."

- England silence Hungarian crowd -
British media reported that Raheem Sterling and Jude Bellingham were targeted with monkey chants as England bounced back from their agonising Euro final defeat by seeing off Hungary 4-0 in Budapest.
The majority of the 60,000 home fans booed Gareth Southgate's players as they took the knee to highlight racial injustice before kick-off, before repeatedly throwing missiles at the visiting team from the stands.
A flare was also launched onto the pitch.
"I didn't hear that (racist chants). I will talk to the boys and see if they heard any of it," England captain Harry Kane told ITV.
"We will have to report it to UEFA as the rules permit. If that is the case, hopefully UEFA come down strong."
Sterling answered the hostile Puskas Arena crowd in the best possible way with a 55th-minute opening goal, before Kane and Harry Maguire both scored headers.
Declan Rice's late strike capped an excellent night on the pitch for England as they maintained their 100 percent record with a fourth straight victory in Group I.
