I am Lvl 22 and I have a driver on my shortlist that is Lvl 21 but I can't buy him. Do know how I can buy him? Please help me.
You can only buy free agents (Drivers or Staff) if you have employed them in your team in the past.
You will have to hope they go to auction but given the number of drivers that are out of contract and the limited numbers on the market I wouldn't hold your breath. Chances are the driver will never go to auction and even if they did you won't know, there is no alert.
Shortlisting is really only any use to allow you to easily find and re-employ drivers and staff if you inadvertently allow their contract to expire.
