Set-pieces are one of the most effective ways of scoring goals on a football pitch. While a direct goal from a dead-ball situation is very much appreciated, one cannot undermine the importance of a goal scored from an indirect free-kick. Players like John Terry, Gary Cahill, Nemanja Vidic and Sergio Ramos have proven just how deadly a player can be in set-piece situations. Defenders pose the greatest threat in such scenarios because of their aerial abilities.Interestingly, a number of top European clubs have struggled with set-pieces this season. Manchester United are one such example. The Red Devils have had more than 100 set-pieces this season but are yet to make them count.However, some clubs have been able to capitalize on the dead-ball situation.
