Ralf Rangnick admits Manchester United could struggle to even draw with Liverpool

Ralf Rangnick admits Manchester United's defensive frailties mean his team could struggle to win even a point when they take on quadruple-chasing Liverpool in the Premier League this week.

United needed a 50th club career hat-trick from veteran attacker Cristiano Ronaldo to defeat relegation-haunted Norwich City 3-2 on Saturday.

Rangnick's side threw away a two-goal advantage at Old Trafford and needed a well-struck free-kick from Ronaldo 14 minutes from time to secure a vital three points in their battle for a top-four spot.

But the German interim manager admitted the defensive weakness shown by his team against the division's bottom club was a concern ahead of Tuesday's game against Liverpool at Anfield.

Jurgen Klopp's side remain on course for four trophies – they have already won the League Cup – as they sit just one point behind table-topping Manchester City and take on Villarreal in the Champions League semi-finals.

The Merseysiders beat City in the FA Cup semi-final at Wembley on Saturday.

“Everybody has seen today's game and everybody knows what kind of team we are playing on Tuesday,” Rangnick said.

“They [Liverpool] have just beaten Man City, they are in the cup final and they might have a chance to win four trophies this season.

“If we play like we did today, it will be very difficult to even get a point.

“This is what we have to be realistic and aware of. We have to be lot better when the opposition is in possession.”
