The Scottish Sun says Hoops boss Neil Lennon has persuaded the teenage full-back to ignore Premier League interest and move to Parkhead. Wales Under-21 starlet Matthews had been linked with Manchester United.
But Cardiff insiders last night confirmed the deal has been DONE for the 19-year-old prospect who is rated in the £4million bracket but can join Celts for a compensation fee of just £200,000.
It is understood Celtic - who already have Welsh international midfielder Joe Ledley on the books from Cardiff - have told the Championship club they plan to negotiate a pre-contract agreement with Matthews to allow him to become a Hoops player on July 1.
