Analyzing football transfers

I’m considering the player profile: a left-footed center-back who’s ball-playing and aggressive. Pairing up with Militao seems promising. The price range is around 50-60 million, but Dortmund appears hesitant. I'm curious about the possibility of Saudi clubs being interested in Rüdiger, although that seems unlikely. I'll aim to provide a short bullet point with concise options and quick analysis. Let's put this together effectively!
