Two days later, Porto signed União de Leiria's coach, José Mourinho, who had previously worked in the club alongside Robson. In his presentation, Mourinho promptly showcased his personality by stating unequivocally that the club would win next season's league title. He kept true to his promise and delivered one of the club's most successful seasons. Fielding the likes of Deco, Ricardo Carvalho, Maniche, and less known players hired from other Portuguese clubs, such as Paulo Ferreira, Pedro Emanuel, Nuno Valente and Derlei, Porto won the 2002–03 Primeira Liga with relative comfort, finishing 11 points ahead of second-placed Benfica. The club also won the UEFA Cup, defeating Celtic in a dramatic extra-time final, to win its second major European title. Mourinho then secured an unprecedented treble for Porto by winning the Taça de Portugal final against his previous club.
