It's mad to think that Roy Keane has not held a managerial position since 2011. While he has been assistance manager with Ireland, Aston Villa, and Nottingham Forest in the intervening years, he has not had the top job since leaving Ipswich nine years ago.
It looked as though he was going to be a quality manager after bursting onto the scene at Sunderland, but it hasn't worked out that way as of yet.
He spent two-and-a-half seasons at the Stadium of Light before an 18-months spell at Ipswich Town. One thing he became known for during this period was signing Irish players.
What we want to know is, can you name every Irish player he signed during his spells at those clubs?
A couple of caveats here. We are only talking about Republic of Ireland players, so the likes of Jonny Evans and David Healy are not included.
We are also only looking for players that he signed while manager, not players who were already at the club when he arrived. The likes of Daryl Murphy and Rory Delap would fall into that category.
To help you out, we have given you the club each player was signed from, with 13 to get in all. You have six minutes.
