West Ham United had Diafra Sakho sent off in the early stages of their Europa League qualifying second leg against Lusitanos, but they lead 1-0 at the break and 4-0 on aggregate in Andorra.
The first chance of the game fell the way of the hosts, who did not manage a single shot on target in the first leg, but tested Darren Randolph inside five minutes as Luis Miguel dos Reis's cross almost caught out the new Hammers stopper.
Sakho, scorer of two goals in the opening leg, was given his marching orders not long after following an off-the-ball incident.
That left Elliot Lee up front on his own and it was the youngster who bagged the only goal of the opening period with a pinpoint finish after being played in by Matt Jarvis.
Moments after scoring his first West Ham goal, Lee almost grabbed his second, but he was denied just as he was about to shoot.
Unless West Ham suffer a collapse in the second half, they will face Maltese side Birkirkara in the next qualifying round.
