Bayern Munich coach Pep Guardiola is full of praise for Benfica midfielder Renato Sanches.
Bayern and Benfica meet in the Champions League this week.
Sanches is expected to join Manchester United at the end of this season, while Manchester City have also been linked.
Incoming City coach Guardiola is well aware of the midfielder's qualities: "Renato and (Nelson) Semedo are two fantastic players and have a great future ahead of them.
"Benfica mix young and experienced people, their organisation is a strong point. They are a great team and my players have been warned."
