Sanches joined Bayern from Benfica last summer for an initial fee of £27.5m, and after a fine display ay Euro 2016 with Portugal, much was expected of the dynamic box-to-box midfielder.
Renato Sanches could be on the move this summer.

With his contract expiring at the end of next season, Sanchez has been heavily linked with a move away from Arsenal this summer with Bayern Munich believed to be keen on him.
