Yeah Barcelona swept in for Suárez before the ban was in effect and sold Alexis for that reason.
Both Real and Atlético have too many high profile attacking players even if they're not getting anyone in (which they most likely will regardless). Real it'll be most likely Isco but even James might be sold, has had some issues in the last weeks and months, also we have his brother-in-law on our books.
Simeone has done a great job giving all of his youngsters some game time this season but one or two of the five or six players I'd have here could probably lured with more game time, even Griezmann who's a nailed on starter could probably triple his wages here.
