Man-marking in set pieces allows for tighter coverage of individual players, making it harder for them to find space and create scoring opportunities. It also allows for more accountability as each player is responsible for marking a specific opponent. However, man-marking can lead to confusion and mismatches if players are not able to track their marks effectively. On the other hand, zonal marking in set pieces allows players to cover specific areas of the field, making it easier to defend against aerial threats and crosses.
