Go for Akinfeev , Adler or Ochoa and on 2nd season january sign Asenjo on free cos usually he wants to leave due to De Gea keeping him out of the team in Athletico. Then on 3rd season you have great nro1 and good backup goalie at your disposal. Then sign some young englishman to be your 3rd to keep homegrown quota. Smithies will do the job perfectly.
On my arsenal game i went for Enyeama first and he did ok, but i wasnt convinced so i sold him for 5m and got Ochoa who kept 10 games clean and i played against likes of Real , Utd and Chelski.
