The former Benfica player enjoyed an impressive campaign with Portugal as they picked up the title, and the Bavarians' chief admitted they were lucky to swoop beforehand
Bayern Munich chairman Karl-Heinz Rummenigge believes the Bundesliga champion would not have been able to afford Renato Sanches had they waited until after Euro 2016.
The Bavarians announced the capture of the Portugal international in May, paying Benfica an initial fee of 35 million euro ($38.7 million) for the young midfielder.
Sanches then impressed at Euro 2016 as he played a key role in Portugal's successful finals, winning young player of the tournament, and Rummenigge thinks his price would have gone through the roof had a deal not been in place beforehand.
