Aaron Cresswell has warned his West Ham United teammates to expect a tough test in their Europa League qualifier against Astra Giurgiu.

The Hammers welcome the Romanian outfit to Upton Park tonight for the first leg of the third-round tie.

With the possibility of reaching the group stage edging closer, Cresswell is eager for West Ham to remain focused.

"We want to be in the group stages and there will be better teams as the competition progresses," he told the club's official website.

"It will be a test for us but one we are looking forward to. The fans are turning out in their numbers again and long may it continue.

"It is a game we are looking forward to. We have seen videos of the opposition. They are going to be tough and don't look a bad side."

West Ham start the new Premier League season with a trip to Arsenal on August 9.
