John Barnes has questioned whether Paris Saint-Germain forward Kylian Mbappe would be the right fit for Liverpool.
The Reds have been tipped to make a move for the France international at the end of the season, despite his rumoured £200m valuation.
Mbappe has scored 16 goals in 164 games for Monaco and PSG, while also helping France to World Cup success in 2018, but former Liverpool attacker Barnes does not believe that the youngster has the work ethic to dislodge any of Liverpool's current front three.
"They'll need to sign another forward at some point in case one of the front three leaves but it will have to fit what Klopp wants," Barnes told the Daily Mail. "Kylian Mbappe is fantastic on the ball but would he do the other stuff? I'd suggest if you're a 21-year-old superstar, your attitude isn't going to change.
"Ninety-nine per cent of people wouldn't pick [Jordan] Henderson and [Georginio] Wijnaldum above Kevin De Bruyne and David Silva or even Jack Grealish or James Maddison, but they work for Liverpool.
"Divock Origi and Xherdan Shaqiri came in for the Barcelona semi-final, their attitude was great and they were physically ready. It shows they were training well, waiting for their chance.
"Jurgen [Klopp] creates that environment. One of the bravest things was letting Philippe Coutinho go and not directly replacing him. Liverpool trusted him."
Real Madrid are also reportedly in the running to sign Mbappe, but they are not expected to make an approach until next year due to the financial impact of the coronavirus pandemic.
