West Ham United defender Joey O'Brien has called on his teammates to maintain their intensity for the second leg of their Europa League qualifier against Lusitanos.

Slaven Bilic's men got their campaign off to a winning start with a convincing 3-0 victory over the Andorran side at Upton Park, but O'Brien has admitted that the players were not entirely satisfied with their performance.

He told the club's official website: "We wanted to go out there win the game which we did, and see how many we could get. We could've scored more.

"It was such a great atmosphere, with our fans and a packed stadium, we wanted to do as best we could for them. We will go over there now in similar fashion and make sure we finish what we have started here."

The second leg of the match takes place on Thursday.
