I don't think Dida will want to play for his team (no offense), I tried to sign him with Anderlecht start of game, but he was to greedy (as was Rivaldo) and they signed for other teams, interest in these players is still high despite their age. They got high demands as well.Maybe if you could get Dida for free? he's a great gk even tho' he's old, but he'll probably be a must buy target, but he maybe won't come
Try to get some guys who are free, maybe Dario Zahora? Not sure if it's Dario zahora or Darijo Zahora
