Martinelli hat-trick sends Arsenal past Portsmouth in FA Cup, Man Utd beaten

PORSTMOUTH, England, Jan 11 : Gabriel ‌Martinelli scored his first hat-trick for Arsenal as the Premier League leaders beat second-tier strugglers Portsmouth 4-1 to reach the FA Cup fourth round on Sunday.

The Brazilian was criticised in midweek for his behaviour after Liverpool's Conor Bradley suffered a serious injury near the end of their Premier League clash on Thursday but ended the week in style with his first goals in the FA Cup.

Manchester United bowed out though as they lost 2-1 at home to Brighton and Hove Albion with Danny Welbeck on target against his former club.

It is the first time since the 1981-82 season that United have failed to win a round of either ‌domestic cup competition.

In other third-round ties, West Ham United enjoyed a break from their Premier League ‌woes as they beat second-tier Queens Park Rangers 2-1 after extra time with new signing Valentin Castellanos heading the winner.

Premier League Leeds United beat Derby County 3-1 while third-tier Mansfield Town beat Championship side Sheffield United 4-3 away.

After several shocks already in the third round, including sixth-tier Macclesfield knocking out holders Crystal Palace, another one looked possible when Colby Bishop raised the roof at Fratton Park by putting Portsmouth ahead after three minutes against Arsenal, firing in a rebound after a save by Kepa Arrizabalaga.

"We started the game exactly how we didn't want to, giving them hope and ‍momentum but we managed to turn things around," Arsenal manager Mikel Arteta, who made 10 changes to his starting lineup, told TNT Sports.

"We had to fight back and credit to (Portsmouth) because they make it difficult for us, especially in the early stages."
