NORWICH (Reuters) -Liverpool eased into the new Premier League season as goals by Diogo Jota, Roberto Firmino and Mohamed Salah earned them a 3-0 victory at promoted Norwich City on Saturday. With defensive linchpin Virgil van Dijk back after nine months out with a serious knee injury, Liverpool enjoyed a relatively trouble-free evening at Carrow Road. Norwich had their chances but once Jota gave Liverpool the lead in the 26th minute the visitors were in command. The Egyptian striker has now scored on the opening weekend for the past five seasons -- a Premier League record. "It was a tough game for many reasons and 3-0 sounds comfortable," Van Dijk, who signed a new contract with the Anfield club this week, told Sky Sports.
