LIVERPOOL have stepped up their interest in former Real Madrid goalkeeper Iker Casillas, according to reports in Spain.
The 2010 World Cup-winner, 36, will leave Porto when his contract runs out at the end of the campaign.
And Sport claim Liverpool is considering a move for the Spaniard on a free transfer.
The Reds hammered Porto 5-0 when they met at the Estadio Dragao for the first leg of their Champions League last-16 clash.
Casillas didn’t play in the match, but did come back into the side for the return at Anfield and kept a clean sheet as the sides drew 0-0.
Jurgen Klopp has had issues with his goalkeepers since moving to Anfield in 2015, yet appears to have found a solution in Loris Karius.
The former Mainz stopper has become the established No 1 for Liverpool, with Simon Mignolet as back-up.
However, despite his improvement, the German is still guilty of reckless mistakes, such as wiping out Wilfried Zaha to give away a penalty against Crystal Palace on Saturday.
Klopp is expected to make signing a new goalkeeper his main priority this summer.
Liverpool are one of a number of sides interested in signing Roma’s impressive stopper Alisson.
