This isnt a bug but a fault in the thinking of the programmers if they think this is how tackling is done. You can only normaly tackle away from your half and thats why someone has said you only have one chance to get it right. You see, if you are running alongside an attacker who is going toward your touchline or goal, the tackle action by the defender is away from your goal and he/she (lol, campaign for womens Fifa) is then stranded when you inevitably miss. The tackle action should be toward the ball and the way it currently is, is bad/lazy scripting. Most succesfull tackles are when you come from in front of the defender and into the ball, from toward your half.
