Liverpool held on to beat Arsenal in a stunning Premier League opening-weekend encounter at Emirates Stadium. Theo Walcott fired in the first goal for the Gunners in the 31st minute, moments after missing a penalty. Philippe Coutinho equalised with a brilliant free-kick before Adam Lallana fired in after the break. Coutinho poked in his second and Sadio Mane slammed home, before Arsenal's Alex Oxlade-Chamberlain scored a great solo goal and Calum Chambers headed in. It was billed as the best game of the Premier League opening weekend and more than lived up to expectations.
