Bayern Munich president Uli Hoeness won't rule out spending big in 2020.
Manchester City ace Leroy Sane remains a priority target for Bayern as he recovers from knee surgery.
It's been suggested it could take over 100m to convince City to sell - and Hoeness says Bayern are prepared to accommodate.
"Such a sum would be breaking the barrier," he told 51.
"But I do not think it (the 100m) could stop things, if you act skillfully enough."
