The Birmingham City fan who attacked Jack Grealish has been sentenced to 14 weeks in prison and handed a 10-year ban from football matches.

Paul Mitchell, of Rubery, Worcestershire, pleaded guilty to pitch invasion and assault after punching Aston Villa midfielder Grealish during the Second City derby at St Andrew's on Sunday.

Mitchell, 27, was also ordered to pay £350 in fines and is prohibited from attending games in the United Kingdom for the next decade.

The incident occurred just hours before a man ran across the field of play and pushed Manchester United defender Chris Smalling during their Premier League match against Arsenal at Emirates Stadium.

The Football Association has resolved to work with other authorities in order to provide greater protection for players and match officials.

"This weekend a line has been crossed in terms of fan behaviour," an FA spokesperson said in a statement.

"On Sunday we saw two separate incidents, at Birmingham City and Arsenal, of individuals entering the field of play and assaulting players.

"Not only is it an offence to enter the pitch, which could result in a club ban and criminal charges for the individual, but it also puts the safety of the players at risk.

"This is entirely unacceptable and we strongly condemn both incidents.

"We will be working with the clubs, the leagues and the police to discuss what collectively needs to be done to protect players and officials on the pitch.

"In addition, we have written to both Birmingham City and Arsenal to seek their observations to examine the security measures they had in place."

Police have arrested a man on suspicion of common assault and pitch invasion after he pushed Chris Smalling during Arsenal's win over Manchester United in the Premier League.

The fan ran across the Emirates Stadium turf and made contact with United defender Smalling following Pierre-Emerick Aubameyang's conversion from the penalty spot.

Metropololitan Police confirmed the man is in custody at a north London police station.

A statement from an Arsenal spokesperson announced the club's intention to ban the individual.

It read: "We utterly condemn the behaviour of the individual who ran onto the pitch and approached Chris Smalling during today's match.

"We would like to apologise to Chris and Manchester United, and are pleased that the individual was apprehended and arrested.

"We will be working closely with the Metropolitan Police in their investigation. The individual will also be banned from Arsenal matches home and away."

The incident occured just hours after Jack Grealish was punched by a pitch invader during the Championship clash between Aston Villa and Birmingham City at St Andrew's.

United captain Ashley Young, who was nearby when the spectator approached the celebrating Arsenal players, called on football's authorities to provide greater protection.

"What if they are carrying something? The players will be in danger," Young told beIN Sports.

"I think it's definitely somewthing the FA, the Premier League, FIFA [have to address]. I don't know whether it's extra stewarding or whatever.

"It's obviously a concern with the one earlier today and then the one on Chris. Something has got to be done."

Chris Smalling believes Manchester United's dramatic Champions League win over Paris Saint-Germain on Wednesday will galvanise the club for the remainder of the season.

United claimed a dramatic 3-1 win on Wednesday at Parc des Princes to reach the quarter-finals on away goals after a 3-3 aggregate draw.

Trailing 2-0 from the first leg and without 10 senior players due to injury and suspension, United were 2-1 up thanks to Romelu Lukaku's double before Marcus Rashford struck an injury-time penalty in the second half that was awarded following a VAR review.

After playing his part to help United become the first team in Champions League history to progress in a knockout tie after losing the first leg by two or more goals at home, Smalling is confident that the win will propel them through the season's closing stages.

"After Rashford had scored and we had all gone into the corner, I think I was shouting that much that I felt dizzy," he told Manchester United's official website.

"I went into the changing room after and spoke to Luke [Shaw]. I was saying to him how I felt dizzy and he said the same thing as well.

"It was an unbelievable feeling and an unbelievable moment that will galvanise us until the end of the season.

"I think their players thought there was no way, going into the game, that they could lose. But we knew we had a game plan as a team to frustrate them at times and know that we would get chances on the counter attack.

"I think we could have scored a couple more goals as well. Ultimately, they might have had more of the ball, but I felt like we had the better chances. Full credit to the whole XI and the game plan, to stick to it despite times when we came under pressure.

"I think it all just summed up what this club is about. I think it was a great time to be part of this club, for sure.

"Obviously, there was no trophy at the end of the game, but in terms of games and moments in my career, barring cup finals, that is definitely up there."

Manchester United travel to Emirates Stadium on Sunday to face Arsenal, who are a point and place behind them in fifth.

Ole Gunnar Solskjaer might have restored positivity at Manchester United, but Chris Smalling insists the caretaker manager has a "nasty side".

United won 10 and drew one of their first 11 games after the former striker succeeded Jose Mourinho in December, with his unbeaten run coming to an end against Paris Saint-Germain in the Champions League on Tuesday.

Solskjaer has won praise both for improving United's standard on the pitch and for lifting the morale around Old Trafford following a tough final few months under Mourinho.

But while Smalling says he is "a joy to play under", he claims Solskjaer is not afraid to use a stricter approach when needed.

"I think he has got that sort of nasty side," Smalling told MUTV. "I think every manager has that, the so-called hairdryer treatment when things need a little turnaround. A manager has to have all different sides covered. He's a joy to play under and he's great."

United face Chelsea in the FA Cup on Monday knowing that the competition represents their best chance of ending the season with silverware.

Smalling is confident of a positive result at Stamford Bridge, particularly given they were moments away from a 2-1 win in the league this season before Ross Barkley struck an injury-time equaliser.

"This year, we're making sure we get a trophy and, on Monday, we'll be going all for it," he said.

"The record at Chelsea, you're right, we've not had too many good results there but I thought, earlier in the season, we were so close to winning until the last dying seconds. In general, we played quite well there, so let's kick on and improve on that performance.

"The fact it's Monday night as well means it's got the whole world watching. They'll be looking to improve on last weekend's result [at Manchester City], as we will [after PSG], so it's a big game all around."

Smalling feels primed to play his part for the rest of the season after admitting he rushed back from a broken toe too quickly in December.

"I'm fully healed from the broken toe now. It was good to be available again on Saturday [against Fulham] and get that game under my belt," he said. 

"It's just about managing my next game and getting back up to match fitness. Hopefully, I'll be available for all the games until the end of the season.

"Through the Fulham and Arsenal [home] games, I had injections and then I had more injections for the Liverpool game [at Anfield] but it made the injury worse. So, then it was a case of getting it right and getting back as soon as I can but, first and foremost, making sure it was right."

Manchester United have handed a new contract to defender Chris Smalling, which could keep him at Old Trafford until 2023.

Smalling, 29, has signed a deal running to June 2022, with an option for a one-year extension.

The centre-back joined United from Fulham in 2010 and has won all major trophies in English football during his time with the Red Devils, including the 2010-11 and 2012-13 Premier League titles.

Smalling was also a key member of the team that lifted the Europa League in 2016-17, completing 90 minutes in the final as Jose Mourinho's team beat Ajax 2-0 in Stockholm.

Overall, he has made 307 appearances for United in all competitions, scoring 18 goals.

"This is my ninth season with the club and I am delighted to be continuing my progression with this team," Smalling told United's official website.

"It is a real honour to play for Manchester United and we are all now concentrating on the busy schedule of games throughout the festive period."

Smalling made his international debut in 2011 and has 31 caps for England, although he has fallen out of favour with current boss Gareth Southgate and missed out on a place in the 2018 World Cup squad.

"I am very happy Chris has signed a new contract," Mourinho told his club's website.

"Chris has been with the club for a number of years and is now one of the senior players within our squad."

United travel to Liverpool on Sunday, languishing 16 points behind their old rivals going into the Anfield showdown.

Chris Smalling says Manchester United's never-say-die attitude is reminiscent of life under Alex Ferguson.

The Reds' latest last-gasp win came at Bournemouth on Saturday, where Marcus Rashford’s

Manchester United manager Jose Mourinho has been impressed with Chris Smalling's recent form, though he is not keen on the centre-back's new haircut. 

Manchester United produced arguably their most complete performance of the season as they beat Watford 2-1 at Vicarage Road to end their hosts' 100 per cent start to the campaign.
