The position at which a soccer player becomes a specialist can often be determined by his physical height and stature. However, this is not always the case. A player who is strong and powerful will have different strengths and weaknesses compared to a player shorter in stature but also fast and nimble on his feet. A winning soccer team usually will be made up of a group of players performing to their strengths. A defender must be skilled at tackling. There are three main types of tackles — the jockey, the block and the sliding tackle.
