United extended their unbeaten away Premier League run to 20 matches with a 0-0 draw at Stamford Bridge. Carragher sees great possibilities in the club getting top strikers.
But the result saw the Red Devils fail to score against big-six opposition for the sixth consecutive Premier League fixture.
Bruno Fernandes’ goal from the penalty spot in October’s 6-1 defeat to Tottenham Hotspur is the only time United have scored against any of their big-six rivals in seven games this season.
“If United had [Marcus] Rashford on the left, a new centre-forward, and [Mason] Greenwood supplementing a new right winger, that would address the lack of quality.
“You look at the options. In this country it’s Harry Kane, or Erling Haaland who is coming through. You wonder whether they are players Manchester United should be targeting,” Carragher said on Monday Night Football.
