Barcelona suffered a second consecutive La Liga defeat to blow the title race wide open as Mikel Oyarzabal’s header handed Real Sociedad a 1-0 win over the European champions on Saturday.

Cristiano Ronaldo also kept Real Madrid in the hunt a further point back in third with a goal and two assists in a 4-0 rout of Eibar.

Pressure is now firmly on the Catalans after tasting defeat for the second time in a week after seeing a 39-game unbeaten run snapped by Real Madrid last weekend.

Barcelona have now not won in their last seven visits to Sociedad and lost each of their last four league meetings in San Sebastian.

Just as in last season’s 1-0 win under the tutelage of David Moyes, Sociedad made the perfect start as 18-year-old Oyarzabal soared to power home Xabi Prieto’s cross into the far corner.

Elsewhere, Bayern Munich warmed up for Wednesday’s crucial Champions League quarter-final at Benfica with a 3-1 win at Stuttgart on Saturday to maintain their iron-grip on the Bundesliga title race, while a second-half brace by Lucas Moura handed PSG a 2-0 win away to Guingamp.

In Serie A Paul Pogba struck a second-half winner as Juventus continued their march towards a record-equalling fifth Serie A title with a 2-1 victory at AC Milan on Saturday.

Juventus, who last won five titles on the trot in 1935, are now nine points clear of second-placed Napoli before they host basement side Verona on Sunday.
