The Mirror says BVB are lining up a cut-price swoop to take United misfit Kagawa back to the Bundesliga.
Kagawa has failed to nail down a regular place since joining from Dortmund for £17m two years ago.
Now, Jurgen Klopp is set to offer United £12m for him.
Talks will intensify with Kagawa and United back in Manchester today after their US tour.
