Bayern Munich, Borussia Dortmund, Atletico Madrid and the Gunners have also shown interest in the star, who joined Leipzig from Red Bull Salzburg last June.
RB Leipzig sporting director Ralf Ragnick says that his club are confident of keeping in-demand midfielder Naby Keita beyond the end of the season.
The 22-year-old has been linked with a summer move to either Arsenal or Liverpool as a result, while Bayern Munich are reportedly interested in him too.
"[He has] no release clause in his contract [and] he's still under contract for a long time yet".
The Guinea worldwide was immediately taken to the Uni-Klinik Leipzig hospital with the RBL club doctor for tests.
I don't know if he'll play for us for three or four more years.
He said, "I don't know anything about Bayern interest".
With Bundesliga debutants Leipzig flying high in the table, the sporting director added: "If we qualify for Europe, there's also no reason why Nabi shouldn't play for us next season".
'We wouldn't swap Keita with [Paul] Pogba for our style of play'. Keita shares the same agent as Sadio Mane, which has given Liverpool fans some hope in our pursuit of him.
The Guinea midfielder has scored four goals and produced eight assists in all competitions for the German outfit. With Santi Cazorla being pegged back by injuries and uncertainty surrounding Jack Wilshere's future, a midfield addition could become top priority.
RB Leipzig have issued a hands off warning to Liverpool after the Premier League club expressed interest in midfielder Naby Keita.
