Kevin Phillips has urged Celtic to make Ben Foster their number one target this summer.
The Bhoys are in the market for a goalkeeper following the end of Fraser Forster's loan spell from Southampton.
While the former Newcastle United man is among the contenders to head back to Celtic Park, Neil Lennon is thought to be monitoring a number of other options.
Foster is one who is near the top of that list.
The Watford stopper is out of contract this summer, meaning that the 37-year-old would be available on a free transfer should the Scottish giants be able to agree personal terms with the player.
While a move to Celtic would no doubt be appealing, former Sunderland and Watford striker Kevin Phillips believes that Foster may be reluctant to leave the Premier League, but insists that he should certainly be number one on the Bhoys' shopping list.
Speaking to Football Insider, Phillips said: “I rate Fozzy (Ben Foster). I played with him at Birmingham.
“I think he has had a fantastic season at Watford. He has been there before and now he is having another stint and he would certainly be a great choice, and great at Celtic.
“If I was Neil Lennon and I had to pick out of those three you would look to go for a Ben Foster.
“Whether he would want to leave the Premier League, I am not sure he would. He is playing regularly in the best league in the world. Fozzy is a fantastic goalkeeper.”
GIVEMESPORT'S Phil Spencer says...
Ben Foster would be a brilliant addition for Celtic.
As well as being a top quality goalkeeper, the former Manchester United stopper is a great personality to have both on and off the pitch.
As is the case with football these days, a move is likely to hinge on the financial aspect and that could be a problem for Celtic.
But if they can convince him to move to Glasgow then it would certainly be a top addition.
