On the topic of Career Mode, I haven't played much of it as I haven't enjoyed playing against the computer much on Fifa13 and if I wanted to Sim games I'd play FM, but one player I will recommend is Fred of Internacional in Brazil. He's a 69 rated CAM, your classic little (I believe he was about 5'6) Brazillian, he's very quick, very weak, but he's one of those players with great balance, so even though his strength was about 30, he was rarely knocked over. So physically he was fantastic, very good dribbling and he also scores goals for fun. I signed him for AJ Auxerre of Ligue 2 for 500 grand and a cheap 64 rated player, had him for half a season in which he played 18, scored 15 and assisted 17 (playing on Legendary), then sold him on 5 months after buying him for 13 million to Fulham (and I had competing offers). No idea what his potential is, but I signed him as a 69 and sold him as a 74, so he went up pretty rapidly. Good player for a lower league team as a prospect or someone to make profit on, or to a bigger team as a reserve player.
Viktor Fischer of Ajax is a good player too, LW, deceptively quick for his stats and just an all-round good player, right-footed but has a great weak foot, can dribble, shoot and cross and has gone up quickly for me and hoping he will carry on doing so. Can also play CAM and ST as far as I remember too.
