Celtic boss Neil Lennon has confirmed that goalkeeper Stipe Pletikosa is on trial at the club.
The 32-year old Croatian had an unhappy loan spell with Tottenham last season and is looking to move on from Spartak Moscow after his contract expired.
Lennon, who is in Australia with the Celtic squad for their pre-season tour, said that Pletikosa is someone he will look at closely when he returns.
"Harry Redknapp was raving about Pletikosa so we'll have a look at him," confirmed Lennon.
Pletikosa counts Hajduk Split and Shakhtar Donetsk as two of his other former clubs and has represented Croatia on more than 80 occasions.
