CELTIC teenager Calum Waters has agreed a season-long loan deal with Championship side Dumbarton.
He becomes the fourth Hoops youngster to accept a temporary transfer in the last four days.
Striker Paul McMullan,19, has joined relegated St Mirren for the new campaign while midfielder Connor McManus,19, and frontman Michael Duffy, 20, will spend an initial six months at Alloa.
Left-sided defender Waters, 19, is on the brink of Deila’s first team squad and his progress will continue with Stevie Aitken’s outfit in Scottish football’s second tier.
Sons boss Stevie Aitken said: “I’m delighted to have signed Calum and I’m grateful to Celtic for their co-operation.
“He’s a highly-rated player and everyone at Celtic speaks highly of him so when he became available to us, it was a no-brainer to add Calum to the squad.”
