Celtic are in line for a cash windfall if former star Kieran Tierney joins Real Madrid in a money-spinning switch this summer.
The 24-year-old has turned heads with Arsenal since a £25m transfer in 2019, and his form in the English Premier League has put him on the radar of one of the world's biggest clubs.
And it's set to be good news for Premiership leaders Celtic, who retain a 15 per cent sell-on fee in a player who would likely cost in excess of £50m. That would net his former club a fee of around £7.5m.
