Watched him lot of times last few seasons.
although i have a very hard time believing this statement, considering that he plays in the Bundesliga and for 12th place team Leverkusen and facing 4 months ban but lets assume it is true and you did watch him a couple of times.
and lets say i will ignore Leverkusen and Bundesliga fans and critics opinion about him being under performing lately and his only power is his freekicks and i will listen to your judgement and not them.
how on earth did you manager in 3 - 4 games (again assuming you watch him play and you were monitor him), judge that he is a better player than bona, who is been our best player over the last 3 years,who has serie a experience, and who not only a better dribbler, he has better defensive skills, better scoring skills, more experience, faster and can control the midfield, really how, i will give Bona the edge any time any day just because he stick with us in our lows and he was and still our best midfielder / player.
i believe people in this forum always gonna shit on our best players no matter how good they are or how loyal they've been.
