The opening stages of England's 2022 World Cup qualifier versus Hungary on Tuesday evening was marred by crowd trouble.Around 800 away fans were said to be in attendance at Wembley Stadium and in the first few minutes of the match, a number of them clashed with police and stewards.Journalist Barney Ronay tweeted as the ugly incident unfolded: "The police have been chased out of the Hungary end. Not enough of them and not ready for it."Fortunately, the trouble appeared to subside a tad as the first half progressed, although Ronay did worryingly add on the social media platform: "There is now no policing in the Hungary end. And just a line of seats between away fans and England seats."The Hungarian fans who were involved should be ashamed of themselves and footage of the clash shows just how chaotic things got in the stands at Wembley as the action continued on the pitch.Will Saka become World Class?
