Its good that you're in the champions league..so you can attract some quality players... look for Kara at DM or as a CB. Milan Badelj or Ruben Yttergard Jenssen at CM. Even Christian Eriksen if you want an assist machine. As for strikers, try and get Niang and Fierro, they're simply amazing. Leandro Damiao if he is interested. Or Seydou Doumbia who is also a very good option. In terms of defenders, Romario or Vrsaljko at Rb, they are always my choices, solid and reliable. Bochetti or Otamendi at CB if they are interested in joining you?
