I guess this question has been asked before, but anyway.

You have the max three players from one team in your squad. A player on loan returns to his home club ( De Laet) and now you have four players from the same team!

What happens if anything?

You play and score points as normal, but the next time you try to make a transfer your team will be invalid until you get back to three players per team.

Anyone know what happened to that guy who transferred in a load of players just before they signed for QPR and ended up with about 8 blue and white hoops in his starting line up?

I'll look for the link.
