Arsenal win delayed after crowd trouble as AC Milan start fast in Europa League romp

Kick-off in Arsenal’s 3-1 win against Cologne was delayed for an hour after thousands of ticketless Cologne fans made it hard for ticket-holders to get into Emirates Stadium. About 20,000 Cologne fans came to London, after only 3,000 tickets were allocated to them. Police said four people were arrested for public order offences.

Also, Atalanta struck three times in the first half to hand struggling Everton a 3-0 defeat, Spanish league joint-leaders Real Sociedad crushed Rosenborg 4-0, and Lyon drew with Apollon of Cyprus 1-1.

Cologne sit winless on the bottom of the Bundesliga, but their fans, walled off by security guards in the stadium, were celebrating after only nine minutes when Jhon Cordoba lobbed goalkeeper David Ospina from 40 yards out.

It took Arsenal 40 minutes to reply, through substitute Sead Kolasinac. Alexis Sanchez hit the match-winner, and started the move for the last goal, a rebound effort finished by Hector Bellerin.

“We went to four at the back at half-time and the second half was better,” Arsenal manager Arsene Wenger said. “Kolasinac makes quick decisions, he’s strong in the tackle and quick going forward. He’s settled in quickly and we’re very pleased to have him.”
