Slaven Bilic said West Ham should be proud of their surprise 2-0 derby win over Arsenal but warned "it's only a start".

Bilic looked to be facing a baptism of fire in his first game as a Premier League manager, but the former Croatia head coach masterminded a shock and long-awaited victory over Arsene Wenger's side. West Ham had not beaten Arsenal for eight years before making the short trip to north London, but ended that barren spell courtesy of goals either side of half-time from Cheikhou Kouyate and Mauro Zarate.
"It's a great result for us, a great performance," he said. "You are hoping you are going to start well, because that is the best proof you are doing things right, then the players believe it is the right thing to do.
"To win a London derby against one of the biggest title contenders, against a team we have lost the last nine games against, that sums up a really proud moment for the club and especially for the fans.
"It's only a start, but it's a great start."
Meanwhile, 16-year-old Reece Oxford reflected on his debut after impressing in West Ham's shock victory.
The midfielder, who became West Ham's youngest ever player in Premier League and the second-youngest to start a Premier League match, told Sky Sports: "It was a dream debut, also playing in midfield too.
"I had Winston Reid and Angelo Ogbonna behind me encouraging me. It's an honour really to play for West Ham and to be the youngest. Hopefully I can get more games in."
