that decision is mental. The force used is excessive as there is no need or justification to use any force whatsoever, i.e. he shouldn't be kicking people. To say the force used is not excessive suggests that you can kick anyone you like, as long as it is not too hard. Presumably this must also apply to headbutts, eye gouges etc
Not sure it's worse than divin but what matters is the rules. IF a kick out is a red card then there shouldn't be debate about severity. Beckham's kick out on Simeone was one of the 'girliest' things i have ever seen in fitba and Simeone's reaction was embarrassing as fck but there was never a debate at the time that Beckham had to go.
When is devlins appeal heard?
