Athlai, in light of having to sign at least one player, you should bid for another player, I'd suggest. Of course you can only sign two in total, but this gives you more options if it comes down to it. Considering that your luck has been pretty poor so far.
I'd recommend the same for other teams that have not yet confirmed a player, btw. Unless, of course, you've calculated that no one can afford to outbid you for your prime target.
