As speculation mounts surrounding the possible departure of Spurs captain Hugo Lloris, with the Daily Mirror among those continuing to suggest that an imminent move to Manchester United is on the cards, attention naturally begins to turn to potential replacements.
Making his debut aged sixteen back in 1997, Casillas has gone on to make over 500 appearances for Los Blancos.
Reports emerging from Spanish newspaper Marca suggest that Spurs are among a group of seven clubs interested in luring the Spaniard away from the Santiago Bernabeu, and are believed to have held talks with the player’s agent.
Listed in the article as Spurs’ rivals for the goalkeeper’s signature are: Arsenal, Roma, PSG, Fenerbache, Beskitas and an unnamed Spanish club.
At 34-years old, Casillas is relatively young as far as goalkeepers go, but his dip in performance levels over the last couple of years will be a worry.
He found himself out of favour under Jose Mourinho and was rotated by Carlo Ancelotti for the past two seasons.
Uncharacteristic errors, in big matches, have started to creep into his game and Spurs fans could be forgiven for being underwhelmed by the prospect of swapping Lloris for Casillas.
The sale of Lloris is by no means a given and Daniel Levy will be determined to retain the Frenchman's services. If reports in Spain are to be believed, however, Spurs have been sounding out possible replacements and the Lloris transfer saga seems set to carry on long into the summer.
