The issue with Oliver is that he’s generally afraid to make a controversial decision. He will try not to make a mistake by not making the difficult call. The irony being he then faces huge controversy over non decisions.
The first time I remember seeing him is when he bottled a blatant Fulham penalty late on at Old Trafford which would have seen united drop points in the 2011/12 run in. Every time I’ve seen him since it’s the same, the non penalties against united when Smalling was sent off, the array of red cards and penalties missed in the 1-1 at home to Liverpool in Pep’s first season, the numerous handballs away to Liverpool in 19/20, the missed red card against Kovacic away to Arsenal last season. Always decides not to make the hard call.
Yesterday the smart decision would have been to book Havertz early and calm matters down. The smart call would’ve been to call the arsenal free kick back as soon as it was taken. Once Calafiori scored he was never going to make the hard decision and call it back.
