West Ham United goalkeeper Adrian has warned his teammates to expect a tough test against Sunderland in the Premier League on Saturday.

The Black Cats, who are just one point above the relegation zone, travel to Upton Park for new manager Dick Advocaat's first game in charge.

While he is hopeful that West Ham can end their own seven-game winless run in the top flight, Adrian believes that they will be pushed hard by struggling Sunderland.

"It'll be a tough game because they are playing to avoid relegation," the Spaniard told the club's official website. "We need to stay strong in order to get the three points.

"In the last home game against Chelsea we had good chances to win. Against Manchester United we also played well but the results haven't matched our performances. Next Saturday at home we want to change that."

West Ham have lost their last three games in a row in the Premier League.
