Celtic have slapped a £30million price tag on the head of coveted left-back Kieran Tierney.
The Scotland international features on a list of potential signings for English Premier League side Bournemouth.
And Europa League winners Atletico Madrid will also send a scout to watch the 20-year-old in Saturday's Scottish Cup final at Hampden, with Manchester United and Tottenham also credited with an interest.
Atletico Madrid are in the market for a left-back after losing first-choice Filipe Luis to injury for most of the season, with replacement Lucas Hernandez a natural central defender.
