If we want a prospect CB, I would take in mind Bruno Mendez of Uruguay. Saw him against Brazil and heard he played again in the other friendly as well, El Maestro sees something in him.. 19 year old, still playing in Uruguay, valued at 135k on Transfermarkt. We might pull a great deal.
Also saw U-21 Poland playing Portugal. Another great performance by Żurkowski, probably best player on the winning team. As TOP youngsters from Poland turned out to be decent deals in Serie A, I think everyone should be on the watch. Żurkowski happens to be the best one available.
