I seem to recall Irrati acquired a bit of a reputation on here from earlier posts.
I watched more of the other game and Craig Pawson had a few incidents to adjudicate on. 2 penalty appeals by Basel, a penalty awarded to Shakhtar and
a tight possible offside for Shakhtar's 4th goal. I expect Michael Oliver, who looked as if he'd been in too much sun, was pleased and relieved that none of the penalty / no penalty decisions were considered to be worth a look at the monitor and likely to lead to his changing his decision.
