I was just looking at the last Maderia Cup winning squad & Keith Keane (Luton Town) & Darren O'Dea (Celtic) are not included in sweden squad. Looks like the last merecenary has taken their positions?
I couldn't find info on Keane (FAi.ie sh!te) but can see that O'Dea has put in the effort to at least play at U18. IMO this is a big issue of parachuting mercenaries into the more high profile U21 & senior squads.
Just because some players in the past were mercenaries doesn't make it right to continue the practice.
