Lindsay is hardly going to command a fee that will allow 4 championship players to be recruited. I doubt he is a high earner too. So Lindsay leaving will just free up a space in the 25 man squad.
Are Derby able to pay high fees for players?
“BBC Derby Sport understands that Derby County will be able to operate without restrictions or embargo in the transfer window this summer. Instead, they will be monitored by the EFL against their own budget and business plan.”
