Premier League managers Pep Guardiola, Jurgen Klopp and Eddie Howe have condemned the recent violence in football this week.

The beautiful game has been overshadowed by a recent spate of violent incidents during pitch invasions.

On Tuesday night, a Nottingham Forest fan Robert Biggs headbutted Sheffield United striker Billy Sharp following their Championship play-off semi-final win over the Blades.

He was jailed for 24 weeks for assault occasioning actual bodily harm.

In the Premier League game between Everton and Crystal Palace, Toffees fans stormed the pitch in celebration as they secured safety - goading Palace manager Patrick Viera who then reacted.

Then in the League Two play-off semi-final between Port Vale and Swindon, Vale fans invaded the pitch following their penalty shoot-out win over Town.

Some of the home supporters allegedly assaulted Swindon Town player Mandela Egbo, whilst Harry McKirdy and travelling Town fans were also caught up in violence.

Now, Premier League managers have expressed their views on the incidents.

Speaking ahead of the final day of the season, where the title, final Champions League spot and relegation zone place are still up for grabs, Manchester City manager Pep Guardiola said: “What happened at Goodison Park, Port Vale and the Championship semi-final, there are a lot of emotions and happiness there - some alcohol too.

“I understand Patrick [Vieira] it's difficult. You never know how people will react.

“We are not going to talk about it [what happens if City win the title on Sunday], the fans will behave good either winning or losing."

Speaking about the incident at Everton, Klopp said: “In the 83rd minute, some fathers and sons were on, they lose their minds for their sons too, I didn't get that. It could have been dangerous.

"I'm not sure how you avoid that, I don't want to judge, I understand emotions but for the other team, it's dangerous.

"I really hope we learn from that. It's just like it is. We should make sure absolutely nothing happens. We can celebrate things without threatening ourselves and the opponent."

Newcastle manager Eddie Howe called on football's authorities to "act very quickly" following the recent events, though he has no problem with fans celebrating on the pitch providing they act responsibly.

He said: "I don't mind the celebrational aspect - embracing the success that a team has had is part of football, I've got no issue with that.

"It's the aggression towards the opposition, it's swarms of people around one or two people.

"That doesn't sit well with me at all, that's something [on which] we have to act very quickly because we want to avert potential tragedy.

"I am concerned, I'm concerned for the safety of everyone connected with both teams because it's not something we want to see on a regular basis.

"The scenes at Nottingham Forest, I thought, were shocking to see and at Everton as well.

“I think we're going into dangerous territory where something could happen in a game that has terrible consequences, and I don't think anyone would want to see that.

“I think the authorities have to act quickly to make sure we make the grounds as safe as we can."
