Sorry, but I cannot confirm anything in this case. Havent heard anything until I went to sleep around 3am.
In general, Pjanic is a great player and he surely was on our shortlist to bring more creativity to our midfield besides Thiago. After signing Sanches, the chances to sign another high calibre midfielder r not that big I guess, but I wouldnt rule it out either. That Bayern r going to add a CB and a CM was clear from the beginning, but no idea what further additions they plan. Ideally we would add Pjanic too then our midfield would look like this:
CDM: Kimmich/Alonso
CM: Vidal/Sanches
CAM: Thiago/Pjanic
What makes me sceptical is, that Bayern prob would have closed the deal already. He has a clause, so why wasting time?
