Arsene Wenger hit out at “scandalous” officiating by referee Tasos Sidiropoulos as Arsenal were dumped out of the Champions League having suffered a 10-2 aggregate defeat to Bayern Munich. With the last-16 tie all-but sewn up after the Bundesliga champions ran out 5-1 winners in Germany last month, the pressure on Wenger has intensified after his 10 men lost by the same margin on Tuesday night – the biggest aggregate loss for an English club in the Champions League.
