Bayern Munich will receive a portion of the transfer fee if former striker Lukas Podolski opts to swap Koln for Arsenal in the summer, according to reports in Germany.
Bild claims that the Bavarians inserted a 10 per cent sell-on clause into the deal that saw the Germany international return to his hometown club three years ago.
The Bavarian giants, whom Podolski featured for between 2006 and 2009, would receive €2 million (£1.7m) if the reported €10m (£8.4m) switch materialises, but the parties involved are yet to comment on the story.
The publication has also reported that Arsenal are currently locked in talks with the Germany international over a three-year contract worth €6m (£5m) a year.
Podolski has scored 15 goals in 19 Bundesliga appearances for Koln this season.
