Celtic manager Ronny Deila has told BBC Sport that he is always open to making improvements to his squad, following his decision to take Carlton Cole on trial.
Cole is currently training with the Bhoys following his release by West Ham United, and Deila says that he is always looking to add talent to his ranks.
At the moment it is not known whether Cole will make his move to Celtic a permanent one, but Deila says he has been impressed with the powerful front-man's showing so far.
"We have a good squad but we are always looking to improve," the 40-year-old manager said. "We are happy he is here.
"He is a target man. He's been good in the two exercises I've seen him doing but he needs more time. He hasn't trained for a while."
Cole has been looking for a new club all summer, with West Ham having deemed him to be surplus to requirements at Upton Park and opted against extending his contract.
The Daily Mail recently reported that MLS clubs had shown an interest in Cole, but the striker wants to remain in Britain.
If he does join Celtic, then he will offer them a different option to the current strikers in Deila's squad, and should provide competition for main marksman Leigh Griffiths up front.
Over a lengthy playing career, which has seen him represent the likes of Chelsea and Aston Villa, Cole has made 384 appearances and scored 85 goals.
