Jurgen Klopp must find a way of stopping Dani Ceballos in Liverpool's Premier League clash with Arsenal this weekend.
That's according to Jamie Redknapp, who has identified the midfielder as a star turn in Unai Emery's new look Gunners side.
Arsenal were short on funds this summer compared to their top four rivals but did a remarkable job strengthening their squad.
Nicolas Pepe and David Luiz have already impressed for the Gunners this season following their arrivals, but it is Ceballos who really caught the eye on his debut.
"What a performance from Dani Ceballos on his full Premier League debut," wrote Redknapp in the Daily Mail.
"Arsenal must already be tempted to ask Real Madrid how much it would cost to sign their loanee on a permanent deal."
Arsenal travel to Anfield this weekend to take on European champions Liverpool.
The Reds are firm favourites to win the match, but Redknapp says Klopp needs to keep an eye on Arsenal's new midfielder to ensure victory.
"Jurgen Klopp will watch back Arsenal's win over Burnley and note they need to stop Ceballos at Anfield next week," Redknapp added.
"That will be a great test of the 23-year-old's ability."
