Now, with player trading such a crucial part of increasing revenue, teams are beginning to hold their own in the transfer market and demand more realistic values for their star men, especially those teams who don't have the clout of finances of Celtic and Rangers.
A number of Premiership stars outwith the Old Firm may view this summer as the one they get their move, whether it be to one of the Glasgow giants, down south or abroad.
The likes of Hearts, Hibs and Aberdeen all have key assets who could fetch a pretty penny in the transfer window, making the coming weeks and months fascinating with regards to player reading and recruitment.
It may also show how far Premiership clubs have come in terms of the transfer fees they manage to eke out of their star players.
We have already taken a look at the 12 most valuable Premiership players and, unsurprisingly, the list was made up of Celtic and Rangers players.
Now, using Transfermarkt’s valuation of Scottish Premiership stars which is, admittedly, not nearly 100 per cent accurate, we look at who the league’s most expensive stars are that don’t play for the Old Firm.
The list of ten is somewhat surprising, both in terms of valuations and the personnel who make up the top ten.

5. 8. Tony Watt - £810k - Dundee United
A brilliant first half of the season at Motherwell saw United sign the player on a pre-contract before bringing him to Tannadice in January. Goals dried up but demonstrated his excellence in build-up play. Photo: Craig Foy - SNS Group

6. 7. Nathaniel Atkinson - £810k - Hearts
Had some ups and downs to begin his Tynecastle Park career but has added really positively to the team in an attacking sense as a wing-back. Should become a more influential next campaign on the right. Photo: Craig Foy - SNS Group

7. 6. Christian Ramirez - £900k - Aberdeen
The American’s goals return can’t be knocked after moving from MLS. Form dipped towards the end of the season with question marks over whether he will continue at Aberdeen. Photo: Ross MacDonald - SNS Group

8. Beni Baningime - £900k - Hearts
The midfielder became an instant favourite amongst fans following his move from Everton. A composed, ball-winning presence who was missed when his season ended early due to injury. Photo: Ewan Bootman - SNS Group
