West Ham supporters have been asking why AZ Alkmaar have not been fined or banned by UEFA following the incidents in the second leg of the semi finals.

Others have asked what happened to Frankfurt after their pitch invasion in Germany in the Europa League against West Ham last year.

Frankfurt were told they must play one game behind closed doors – with the penalty suspended for two years – and were fined £69,000 for six offences relating to their fans.

European football’s governing body at the time announced Moyes would receive a one-game suspension for unsporting conduct while Rice received a two-match ban for abusing a referee in the second leg of last month’s semi-final defeat. West Ham were also fined £1,502 for the throwing of fireworks at the semi final.

On AZ Alkmaar’s punishment the UEFA Ethics and Disciplinary committee agreed to delay their investigation until after the Europa Conference League final to prevent any interference from any players facing suspension.

UEFA said it was waiting for reports from police and other stakeholders as well as reviewing hours of CCTV footage.  AZ Alkmaar have banned 43 supporters for life.

UEFA are likely to appoint an Inspector to carry out an thorough investigation and this will add to the amount of time before the verdict or findings are known.
