As it so happens, just yesterday I listened to a podcast about FC Dallas in which a US football blogger close to the club estimated that Pepi will be likely sold to Europe this winter, with a probability of 60-70%, if not next summer.
But I haven't read anything about Bayern or any Bundesliga club. Bayern's striker succession plan is clear, Haaland to succeed Lewandowski in 2022 or 2023
From what the guy said about Pepi in that podcast, don't think he should go to England, they don't appreciate attackers who excel in combination play and not so much through individual actions.
With that name, I think he should go to Barca.
Edit: actually there's stuff in BILD about Wolfsburg being after him; Bayern, Sampdoria and Ajax are mentioned by transfermarkt. Don't think Bayern would make much sense for him. But living in Wolfsburg, I wouldn't wish that on my worst enemy. How expensive you think he would be?
