Sadio Mane and Curtis Jones struck in the final 20 minutes to ensure Liverpool marked their first match at Anfield since being crowned Premier League champions with a 2-0 win over struggling Aston Villa on Sunday.
According to various media in Barcelona, the renewal of the Spanish manager with Al-Sadd includes a clause which would allow him to move to the Camp Nou without problems in case they want to appoint him.
Back in April 2014, Barça were still in contention for the league title. Emotionally shattered by the death of Tito Vilanova and the two goals for Villarreal pinned Barça back, but two own goals and a third from Messi proved enough to win the three points. A racist incident marred the match.
