When your at the match you can usually tell by watching it plus player reactions and for me it didn't look bad, bit naughty but never a red. Plus opposition players reactions are a great indicator and I can't remember one appealing as if he should be sent off! Funny how refs get influenced, there was a handball near me in the east stand and the ref took an age to give it, almost like the crowd swayed him, plus love the old point at the ball when the opposition have a corner and the ref comes to check!! Our refs have been a joke this season as a fan you just want consistency.
