Barcelona 2-0 Porto
(Messi 39, Fàbregas 89)
Barcelona added yet another trophy to their roll of honour under Josep Guardiola, their second win in three years and fourth overall, as they became the first club to take part eight times.
Fresh from becoming the first recipient of the UEFA Best Player in Europe Award, Lionel Messi was the epitome of coolness on a sweltering night in Monaco as he seized upon Fredy Guarín's back pass, jinked his way past Helton and rolled in the 39th-minute opener. The UEFA Europa League winners were still in the contest until the 86th minute, when Rolando collected a second yellow card and Porto's first red. Barça wasted little time capitalising, substitute Cesc Fàbregas finishing delightfully before Guarín was dismissed in the final minute for a sliding challenge on Javier Mascherano.
Guardiola said: "To win all the titles these guys have in the last three years you need plenty of things, but one of them is a player who can drag everyone along. We have Leo, and when you add the others then they are amazing."
