The midfielder returned to the starting XI on Sunday evening, with Jurgen Klopp deploying him at centre-back.
Fabinho’s deployment at the heart of Liverpool’s defence – which was down to Liverpool’s ongoing defensive crisis – concerned Carragher as the former Monaco man, who had just recovered from a hamstring injury, would have to deal with the pace of Foxes hitman Jamie Vardy.
“It’s an interesting decision,” Carragher said of Fabinho’s deployment at centre-back.
“He has had a hamstring problem and you are certainly going to test your hamstring against Jamie Vardy.
“I thought there was a case for Fabinho going into midfield on his first game back…the midfield certainly isn’t as strong as normal.”
Fabinho’s hamstring, however, held up just fine – with the 27-year-old keeping pace and marshalling Vardy well when required.

Klopp was delighted with the victory, telling Sky Sports, he said: “I think the fact that coming into this game, there was talk of Leicester ending this unbeaten run or Liverpool dropping points.
“Psychologically this feels like a big win. It almost feels like the season starts now.
“Not just this season, but every season once you get the international football out of the way, teams can get into a real run and gather some real momentum.
“It did feel like a big win, and the fact that Manchester City lost this weekend, who I still feel are Liverpool’s biggest title rivals.”
Liverpool will be back in action on Wednesday night, welcoming Atalanta to Anfield for their fourth Champions League Group D match.
