Rangers surprising £2m transfer deficit on Ben Davies deal as Celtic’ summer business meets market value

Celtic and Rangers have both had busy summer transfer windows so far as they prepare for the new Scottish Premiership season.

Ange Postecoglou has spent significant transfer fees on Alexandro Bernabéi, Jota and Cameron Carter-Vickers while also securing the likes of Aaron Mooy and Benji Siegrist for free.

Meanwhile, the Ibrox side have received a decent fee from Southampton for Joe Aribo and reinvested that cash into the signings of Ben Davies, Rabbi Matondo and Antonio Colak.

Aberdeen and Hibs have also seen players leave for seven figure fees this window.

However, do the sums of cash paid for the individual players reflect good financial business by the clubs who have purchased them?

Comparing the reported fee that was paid to the player to their supposed ‘market value’ at the time, we can look at if clubs have overpaid for the individual or have secured themselves a good deal.
