Southampton’s Championship play-off win over West Brom descends into CHAOS as police are forced to separate supporters after a pitch invasion that sees missiles thrown

Southampton and West Brom fans appeared to throw missiles at each other as the Saints celebrated booking their place in the Championship play-off final.

Russell Martin’s side dominated the second leg at St Mary’s on Friday evening, winning 3-1 on the evening thanks to a goal and brace from Adam Armstrong’s Will Smallbone.

They take on Leeds at Wembley next weekend as both sides aim for an immediate return to the Premier League after last season’s relegation.

After the match whistle, hundreds of home fans stormed the pitch to celebrate their side reaching the final, appearing to chase away the supporters before the scenes turned ugly.

Footage from social media appeared to show a rocket being thrown into a crowd on the pitch from what appeared to be the away corner, while a supporter threw another into the stands.

It is unclear whether it was the same missile fired in response.

Other footage showed stewards and police stopping Southampton fans from going to the away match, with heartfelt chants of ‘Albion’ in videos shared online.

Photos showed fans of the away team trying to get onto the pitch.

It was a delayed pitch invasion, with the Southampton side initially congratulating each other after managers Russell Martin and Carlos Corberan shook hands.

Smallbone was all smiles as he made his way from the substitutes bench to the pitch before the first group of fans took to the pitch.

More and more began to enter the field of play, with supporters holding flags aloft and a flare also visible on the field.

The home supporters seemed to excite the away match full of fans who will have to see their team in championship action again next season.

Both Southampton and West Brom have been contacted for comment.

West Brom started the match well, deploying a low block in an attempt to resist the hosts’ possession-based play.

Initially the plan worked, with the score at 0-0 at half-time, mirroring the scoreline from last week’s first leg at the Hawthrons.

However, Smallbone opened the scoring in the 49th minute, meaning the visitors needed to score if they were to at least take the match to extra time.

Armstrong scored his brace to take the game away from West Brom, with Cedric Kirpe’s goal standing in vain deep into stoppage time.
