Liverpool face Nottingham Forest on Saturday afternoon at Anfield, but many are fearful that the side could suffer a sixth defeat in seven Premier League games under manager Arne Slot.
The Reds sit 8th in the table, below rivals Manchester United and as their title hopes slip away to league leaders Arsenal, Carragher has sent a warning to slot and his side.
Speaking on The Overlap podcast, Carragher revealed that Liverpool may not have the squad needed to win the league and should search for improvements in the January window.
“I think there are lots of little things. But if we’re being honest, looking at the games they’ve lost and the type of games they’ve lost, they can’t handle the physicality of the Premier League.
“That’s his football. He’s trying to push Liverpool one way, and I think the Premier League has gone back in terms of physicality.
“I don’t think this group of players is equipped to win the Premier League this year, even with the points and how far behind they are. Maybe in January, more physicality, more pace, more power.
“I think if Liverpool don’t sign a defender in January, they could miss out on the Champions League.”
Liverpool have been linked with Bournemouth’s Antoine Semenyo and Crystal Palace’s Marc Guehi who could provide the quality needed to forge a title push if signed in January.
Defeats to Crystal Palace, Brentford, Manchester United, Chelsea and Manchester City have arrived over the last few weeks are not good enough for title challengers and Slot will be looking at his options over the next few months.
