@Connor will explain this better.
But it happens
Is Connor an agent? Now leaking interest in Digne to force Celtic to play ball over Tierney makes sense.
Interest and bids get leaked via embargo’s in a bid to move a club on. For example, when we were linked with Digne in the first place, it very much seemed like a ploy because Celtic were demanding 25 million up front.
So, if Celtic see that Everton have switched attention elsewhere but are willing to pay in the region of the fee they want for their player, they may climb down from their demands and come down to the bidding clubs level.
Happens with every transfer.
