andrew1957 With regard to the penalty. Even if the trip was accidental by the laws of the game it is still a penalty. A foul is a foul whether accidental or not.
Not sure that's entirely accurate.
what about the 'careless, reckless, excessive' test ?
Agree that the consideration of intent has been removed from the law but not every bit of contact is now a foul, which is kind of what you are suggesting. If the Bristol defender is just running normally in a straight line and Samuel cuts across him and tangles with his foot then Samuel has been 'tripped' but I would not consider it a foul using the criteria in the laws.
