The 20-year-old enjoyed a breakthrough season in 2013/14, having swapped life at Bayern Munich for that in Leverkusen.
He proved himself capable of competing at a Bundesliga level on a regular basis, netting three times in 29 appearances.
Can's efforts have not gone unnoticed, though, with his potential sparking interest from afar.
Liverpool hope that by moving early they can steal a march on their rivals, with Bayern having included a clause in their sale of Can which allows them to bring him back in 2015 if they so wish.
Leverkusen general manager Rudi Voller claims to have been offered no indication by those at the Allianz Arena that they will be looking to reacquire the youngster and insists no formal approach has been received as yet from Anfield.
He told BILD: "We are aware of the interest from Liverpool, but we haven't had anything concrete yet.
"It's a fact that Emre Can has a certain clause in his contract, but there is no decision imminent.
"I have been in touch with Karl-Heinz Rummenigge about Emre Can and Bayern are of the opinion that it would be good for the player to remain at Bayer Leverkusen."
