England moved five points clear at the top of World Cup qualifying Group I after a comfortable 4-0 win over Hungary at the Puskas Arena on Thursday with the hosts possibly set to face further sanctions after more crowd issues.
Raheem Sterling put England ahead in the 55th minute, after a frustrating first half, slotting home a low pull-back from Mason Mount.
Sterling was the provider for England's second eight minutes later, when his deflected cross was headed in by a stooping Harry Kane.
Harry Maguire made it 3-0 in the 69th minute with a header from a Luke Shaw corner and Declan Rice added the fourth with a shot from outside the box which got through the body of keeper Peter Gulacsi.
Hungary, already facing two games behind closed doors in UEFA competition after incidents at their national stadium during Euro 2020, could face sanctions from FIFA after fans threw objects at England players on two occasions.
British broadcaster ITV also said racist "monkey noises" were aimed at Sterling and England substitute Jude Bellingham from the hardcore "ultras" behind the goal.
Afterwards, English captain Harry Kane, who said that he didn't hear any racist chants, hopes that heavy sanctions follow if it was the case.
"I didn't hear that," he told ITV. "I'll talk to the boys and see if they heard any of it.
"Look, we'll have to report it to UEFA as (that’s) the rules with it. If it's the case then hopefully UEFA can come down strong."
England defender John Stones, who won his 50th cap in Budapest, echoed captain Kane's comments.
"I personally didn't hear it, I've been told about it after," he said.
"It is so sad to think that this happens at our games and I hope UEFA and whoever needs to take care of it does and I'm sure they will.
"We stand together as a team and we will continue fighting for what we believe in as a team and what we believe is right."
