Pedro scored a hat-trick as Barcelona made light work of Segunda B outfit Huesca to reach round five of the Copa del Rey this evening.

The Spanish international opened the scoring on 20 minutes after Munir El Haddadi fired a perfect cross, which the attacker headed into the corner.

Pedro doubled Barca's lead moments later when he collected Andres Iniesta's pinpoint pass before finding the bottom corner of the net.

Luis Enrique's men made it three in the 29th minute thanks to Martin Montoya's cross for Sergi Roberto, who calmly beat Dani Jimenez.

Iniesta got in on the act with Barca's fourth on 39 minutes and with half time approaching, the Catalan giants made it five with Pedro completing a hat-trick before the interval.

Adriano netted Barcelona's sixth after a rampaging run ended with a rasping drive into the top corner.

Teenager Adama Traore got on the scoresheet late in the game with a neat finish before fellow youngster Sandro Ramirez added an eighth goal on the night.

Huesca did at least avoid a whitewash as defender Carlos David scored for the minnows with four minutes remaining.

However, it was Barca who reach the fifth round of the competition without being tested.
