Hello NL,
As we all know the transfer market is open and clubs are buying and selling to their own benefit. Barcelona and Liverpool have been on the news line every day pertaining Coutinho. My question now is that, Coutinho has played the Champion league with Liverpool, is there any means he can also play for Barcelona this same season or till another season again? Is there any rule that says if for example Barcelona sign more than three different players that have played the champion league for previous clubs, Barcelona will be allowed to select one to play in the champions league for that same season?

Need your clarification pls, trust my NL people
