I always try to conclude incompetence, rather than bias, but they are testing me.
The "handball" and non-offside are bad enough, but let's not forget, Harry Maguire had Patson Daka in a smelly cuddle in the box the first half.
If it had been Faes on Fernandes, Bruno would have dropped to the floor, screamed and then jumped up to take the penalty.
Instead, the ref looked directly at it, checked the badge, and shrugged.
