Milan: Sampdoria completed their first double derby triumph over city rivals Genoa in 57 years on Saturday thanks to a 1-0 win.

Luis Muriel scored the only goal of the game on 71 minutes after breaking away from a poor tackle from Ezequiel Munoz to drive the ball past Eugenio Lamanna in the Genoa goal.

The Colombian striker was booked for his extravagant celebrations but that didn’t dampen Sampdoria fans’ joy after their side had defeated Genoa twice in the same seasons for the first time since 1960.

Sampdoria are up to ninth place in Serie A while Genoa are down in 15th but 14 points above the relegation zone.

Juventus went 11 points clear on Friday when a contentious injury time penalty gave them a 2-1 win over 10-man AC Milan and a 31st successive home triumph.

The defending champions looked set to be held by their old rivals, who had stunned the 32-time Serie A winners 1-0 at the San Siro earlier in the season, after Carlos Bacca had cancelled out Medhi Benatia’s opener for the league leaders.

But in the closing minutes, Milan lost Jose Sousa to a red card for lashing out at Kwadwo Asamoah before Mattia De Sciglio was penalised for hand ball.

Argentine striker Paulo Dybala kept his nerve to slot the penalty past teenage goalkeeper Gianluigi Donnarumma who had pulled off a series of stunning saves to keep Milan in the game.
