I really disagree with the Mentality decrease. Even though I haven't seen much of him in the Bundesliga, here in the Czech league he always was a mentally strong player who never gave up and kept on fighting and running till the end. Which is also why Stamina shouldn't be lowered either - unless we're taking his injuries into consideration. I mean, when he recovers from the injuries, his Stamina will obviously be low, but if he manages to get back to fitness and regain his old level, he surely should have at least
I'm a bit unsure on Teamwork too but he does tend to stick to the side mostly so I guess you're right there.
Also, I sadly have to agree with Condition 5, and I'm pretty positive he needs IT: C as well.
