Jamie Carragher explains why Man United fans should be concerned about Ralf Rangnick

Manchester United supporters have cause for concern after Monday’s toothless performance against a leaky Newcastle United defence, according to Jamie Carragher.

The Red Devils had to settle for a point at St James’ Park as Edinson Cavani came off the bench in the second half to cancel out Allan Saint-Maximin’s early opener.

Alarmingly, Ralf Rangnick’s side managed just four shots on target compared to Newcastle’s eight and they were grateful for David de Gea’s brilliance in goal despite having 69 per cent of possession.

Rangnick has taken charge of four games since his appointment as interim manager in late November, but United have not scored more than once in any of those fixtures.

That is despite the German having a star-studded squad at his disposal which includes the likes of Cristiano Ronaldo, Bruno Fernandes and Marcus Rashford.

Carragher believes this lack of attacking threat should worry the Old Trafford faithful and pointed out the Red Devils only scored one past a Norwich side which let in five goals against Arsenal on Boxing Day.

“The thing that would worry me as a Manchester United fan is the lack of chances they’re creating in games,” the former Liverpool and England defender told Sky Sports.

“You’ve also got to think of the opposition they’re playing again. This is a depleted Newcastle team who have conceded 11 in the last three games.

“You look at Norwich who Manchester United never really created anything against, they’ve just conceded five against Arsenal. That would be the worry for me.”

Rangnick’s other games in the dugout were a 1-0 victory over Crystal Palace in the Premier League and a 1-1 draw with Young Boys in the Champions League.

The former RB Leipzig boss has used his regular 4-2-2-2 system throughout the early stages of his Manchester United tenure, but Carragher suspects this is not playing to Ronaldo’s strengths.

“You think of the role of Cristiano Ronaldo this season, the amount of times he’s saved Manchester United with big goals – he got the penalty at Norwich but he hasn’t really had many chances,” the 43-year-old added.

“If you’re not creating much for him…he’s a killer, deadly in the box, but if you’re not creating too much, he’s not that involved in the game.”

Ronaldo, 36, was visibly frustrated by his lack of service during the clash with the Magpies and gestured angrily at Rashford after the England international overhit a pass in the first half.
