Ballack is certainly a hit or miss in-game. Sometimes he's an absolute general banging in goals left and right, making beautiful passes, and showing a presence on defense. Most of the time he's a ghost, nowhere to be seen, not clutch at all, unable to complete fairly average passes. Certainly a bit disappointing for an icon, especially since I play him next to Guardiola who has never had issues. In my opinion steer clear, there are plenty of cards that will play similar to better at a fraction of the cost.
scores the occasional world-class goal
fairly strong on the ball but completely incapable of muscling the opposition of the ball because he can't catch up to them
decent passing when he's playing well
Agility and Balance: make him feel slower and clunkier than he should feel. Don't expect to be able to hold the ball for longer than a second, pass quickly or he'll lose the ball to any defender with a pulse
strength: with 86 physical you would expect him to be a rock on the ball, he can certainly shield well but lacks the ability muscle attackers off the ball
passing: certainly underwhelming, short passing is great but frequently plays horrible through balls
pace: he's slow, easy as that, his low agility and balance don't help either
