You make it sound as if it is Ivanovic's fault for being bitten. If he had decked Suarez, he would have been quite rightly sent off. Thank God he has got some self control.
And I think 10 games is too much - out of proportion when compared to career threatening tackles
Does intent play a part in lenghty suspensions for career threatening tackles? If so, this will be harder to demonstrate than biting someone and may explain why a bite gets more than a tackle?
