West Ham United manager Slaven Bilic has claimed that his side should have reacted better after going down to 10 men in their Europa League clash against Astra Giurgiu, which finished 2-2.
Bilic told BBC Sport: "We definitely played well in the first hour, but the game lasts 90 minutes and we had to react better to going down to 10 men.
"We played well until the moment we had a player sent off, we were dominating the game. They scored one great goal and an own goal, but it was a different game after they scored the first one."
Joey O'Brien and Valencia were both substituted with injuries, the latter appearing potentially serious.
