Bayern Munich, Paris St Germain and a number of English clubs have asked to be kept informed if Kenedy is ever made available for sale.
The Brazilian winger has made a huge impact at St James' Park since arriving from Chelsea on loan in January, with Newcastle fans hoping he can be signed on a permanent basis.
But Sky Sports News understands Bayern and PSG have both asked to be kept aware of any developments if Chelsea agree to let him go - although no bids have been tabled to date.
Arjen Robben and Franck Ribery are both out of contract in the summer, and Bayern are keen to find long-term replacements for their talismanic wingers.
Since moving to Newcastle three months ago, Kenedy has scored two goals in eight appearances and helped Rafa Benitez's side move ten points above the relegation zone, with just six games to play.
The 22-year-old has found first-team opportunities far easier to come by at St James' Park than he has at Chelsea - he has made only 27 appearances since moving to Stamford Bridge in August 2015.
But with Antonio Conte's future still in doubt, Kenedy may bide his time before committing to a move away from Stamford Bridge.
