#5 Fabinho
Of the five potential replacements Liverpool could pursue for Can, Monaco's Fabinho could just be the easiest to sign.
The Brazilian, capable of playing both as a midfielder and right-back, revealed that this season will be his last with the Ligue 1 side as he expects to move to another club.
Fabinho is a versatile player gifted in both defending and attacking. He possesses a very good aerial ability, alongside good passing and vision - qualities which have shined through for Monaco both in the league and in the Champions' League.
Obtaining his signature may be difficult as Manchester United are just one of the clubs reportedly interested in the Brazilian. Either way, Fabinho would make a decent signing for Liverpool and a suitable replacement for their current No. 23.
