Sanchez stunner makes Arsenal worth the wait

Kick-off was delayed by an hour after thousands of travelling fans arrived at the stadium without tickets after marching through London.

There were then scuffles with stewards as some supporters, who had managed to get into the stands, attempted to force their way into the away section.

The Bundesliga club have been punished for crowd disturbances, setting off fireworks, throwing objects and acts of damage.

In addition to the fine, Cologne has been given a ban from selling tickets to an away game in UEFA competition, which has been deferred for two years. They have also been instructed to settle with Arsenal over damage caused by fans.

The Gunners were charged for a blocked stairwell in the away section but will face no further punishment.

Skenderbeu will play their next home UEFA match behind closed doors after been found guilty of racist behaviour, illicit chants and setting off fireworks against Partizan. It has also been fined $A91,000.

Braga, meanwhile, has been ordered to close part of their stadium and display an '#EqualGame' banner for its next European match after racist behaviour against Ludogorets, while head coach Abel Ferreira has been given a one-game ban after being sent to the stands.

Shakhtar Donetsk must pay a $A19,000 fine for fireworks offences in its UEFA Champions League match with Napoli.
