Speaking on Sky Sports' Monday Night Football (h/t the Daily Mail), Carragher reflected on Sturridge's struggles in the match:
This was a massive opportunity for Daniel Sturridge on his 100th appearance for Liverpool. Last week with England against Slovenia he failed to impress.
At Anfield he found it very difficult to get a touch and when he did it wasn't always pretty or productive. There was a moment shortly before half-time when he tried to control the ball following a tidy pass from Philippe Coutinho, only for it to trickle into the path of Paul Pogba who darted away from the striker.
Liverpool's fans made their frustrations known. There's a concern that he can't do what Jurgen Klopp wants. He certainly made life difficult for himself.
Prior to the game, Carragher had raised more than a few eyebrows with his claim that "inside the box, he's as good as Sergio Aguero when it comes to finishing," though he noted the England international still had to work on the rest of his game, per the Telegraph's Callum Davis.
Here's a summary of the reaction to his comparison with the Manchester City star:
Sturridge's goals-per-minutes record would suggest Carragher's notion isn't quite as outlandish as it may seem, though, per Sky Sports Statto:
He has struggled for form this season, and his only goals have come against Burton Albion in the EFL Cup. In the Premier League, he has now gone 615 minutes without scoring.
On Monday, Liverpool's best chances fell to Coutinho, Roberto Firmino and Emre Can. As BBC's Match of the Day revealed, Sturridge cut an isolated figure up front:
Per the Liverpool Echo's Ian Doyle, Klopp sympathised with his player: "It was a really difficult game for a striker, the way we played it wasn't easy to enjoy for a striker. In the first half Phil made a brilliant run and wanted to pass to Daniel but [Sadio] Mane was free on the right."
While his isolation was partially because of the way United stifled Liverpool, it also shows that Sturridge is often unwilling to do the selfless running or tracking back Klopp requires of his team.
Gianluca Di Marzio's Joseph Musker believes as much:
The striker has netted 56 goals in 100 games for Liverpool in all competitions, and he's the most clinical player in their squad by some distance.
However, he's not a player who fits in with Klopp's ethos, and it's difficult to see him turning his fortunes at Anfield around.
Indeed, if he were still finding the net each week it might be a different story, but his early struggles this season will make it difficult for him to continue getting in the team when he offers little else.
