Lionel Messi and hat-trick hero Luis Suarez were in sensational form as they helped Barcelona start their title defence with a crushing 6-2 win over Real Betis at the Camp Nou on Saturday.

Messi scored twice and set up another goal, dominating proceedings, while Suarez added three of his own after Arda Turan's opener.

Ruben Castro struck a brace for Betis but at no stage of the game did it seem like the visitors had enough to prevent Luis Enrique's team from running amok on the opening day of the new Spanish season.

New signings Samuel Umtiti and Denis Suarez started for Barcelona, standing in for Javier Mascherano and Andres Iniesta respectively, as Barcelona battled with a long list of absences.

Regardless, it took just five minutes for the hosts to open the scoring, with Turan putting the finishing touch on a fine move. Messi scooped the ball diagonally into the area, finding the marauding Jordi Alba, who cut it back for Turan to prod home.

While Turan is starting to come to life in a Barca shirt, goalkeeper Claudio Bravo is set to end his time at the Camp Nou, with a move to Manchester City reported to be close.

Barcelona fans chanted for him to stay as he prepared to defend Ruben Castro's free-kick, but the Chilean goalkeeper got nowhere near it as the ball flew into the top-right corner.

The hosts reacted instantly. Turan had a half-chance to restore Barcelona's lead but couldn't direct Sergi Roberto's raking low cross on target, before Denis Suarez had a strike deflected over and Messi cracked a strike against the crossbar.
