Super Stefan. I use Lainer with guardian and he is a fantastic player. Very relliable and always wins the tackle at important moments. I did his SBC for 140K and it was totally worth it.
Pace. Feels very quick running back but also on the ball.
Defending. He is always in the right place at the time. His standing and sliding tackles are perfect, every time. I use him with guardian so his defensive awareness and interceptions are also improved.
Dribbling. This was the biggest surprise for me, because he is also very good at dribbling. His agility and balance are very good and combined with improved ballcontrol and dribbling and with very good pace, his dribbling is worldclass.
Passing. His passing is solid and the 4* weakfoot is very handy so he can pass the ball with both feet.
Stamina and aggression. Both 99 stats and you can feel it. Nothing more to say.
Shooting. For a rightback his shooting is very good, his shotpower is high which is very nice.
Lainer has no real cons, but more like not-perfect stats, such as:
Strength. It is 78, it feels like 85 but it isn't 99.
No 4* skills. Doesn't matter at all because of his dribbling.
