While the transfer market has exploded in recent years, that hasn't really applied to Irish players. Not many of our internationals have moved for money over the past few seasons.
How familiar are you with the transfers of Irish players?
We want you to name the 15 most expensive Irish players based on their highest transfer fee, with some of them quite tricky.
To be clear, this only counts the most expensive fee paid for each player, so each player will only appear on the list once.
If it were counting the most expensive deals, some players would appear multiple times.
You will have seven minutes to get them all.
