Liverpool midfielder Gini Wijnaldum says they will not under-estimate Manchester United at Old Trafford tomorrow.

United have made their worst start to a Premier League campaign, but Wijnaldum says Liverpool still respect them.

“The way we handle every match is to respect the opponent and give 100 per cent," he said. “We try to do everything as good as possible, to work as hard as possible.

“Every game in the Premier League is tough. Look at the results we have had. I can't remember a game where it was easy.

"We have won them all so far because we give everything and were totally concentrated. Also we have had a little bit of luck."

United's decline is a shock to those fans who grew up during the trophy-laden years of Sir Alex Ferguson and Wijnaldum claims it could happen to any big club - even Liverpool.

“It can happen to anyone," he said. “It could happen to Liverpool, or Manchester United. It has happened to big clubs in Holland, but I don't really think about it. I concentrate more on Liverpool."
