Liverpool are the latest team who are said to have contacted Eintracht Frankfurt over a deal for Jesper Lindstrom.
The attacking midfielder is also a summer transfer target for the Reds' Premier League rivals Arsenal.
Per Ekstra Bladet in Denmark, the 23-year-old has the pick of the two Premier League clubs.
He is available for a fee of around 35-40 million as a base fee, along with add-ons.
Eintracht want to ensure they are getting a big deal for a player they have developed.
If the 23-year-old does move on, then he will be hoping to leave for a team where he can play regularly next season.
