Michael Olise will have to follow a strict rule if he signs for Bayern Munich.
The highly rated 22-year-old attracted interest from Premier League clubs including Chelsea and Newcastle.
However, Bayern have entered negotiations with Crystal Palace for Olise and have reportedly triggered his £55million release clause.
The winger made a tremendous impact for Palace last season as he scored ten goals and provided six assists in 19 Premier League games.
Olise could now be set for a lucrative move to Bayern, which, according to journalist Christian Falk, would see him earn £220,000-a-week while playing for Vincent Kompany's side.
