This time last year, Aberdeen cashed in on Jonny Hayes selling him to Celtic for a fee of just £1 million. And although the 30-year-old never impressed in the green and white jersey, starting six league games before suffering a broken leg which ended his season, there is no doubt that Hayes looked like great value at the time.
So this perhaps explains why Aberdeen is determined to attach a hefty price tag to Scott McKenna this summer.
The Daily Record claims that McKenna, who started the season as a newbie at Aberdeen and ended it wearing the armband for Scotland in a friendly clash against Mexico, has been valued at £10 million.
But that should not discourage Celtic from raiding the camp of the closest Premiership rivals for the second year in a row.
Celtic needs to increase the quality of their centre-back this summer with the jury still out on Jack Hendry and Marvin Compper. Dedryck Boyata, however, is in the final year of his current deal and has been linked with a £7 million transfer to Lazio by Radio Sei.
So 21-year-old McKenna, left-footed, ball-playing defender with terrific potential, could be the perfect partner for either Jozo Simunovic or Kristoffer Ajer.
His £10 million asking price means Celtic would be compelled to break their transfer record for the second time this summer but, should McKenna become a better player under Rodgers, he would be worth every dime.
