Liverpool will explore the possibility of bringing forward Naby Keita's move from RB Leipzig.
The Anfield club paid £57million to sign the Senegal midfielder last summer and he has remained on loan at Leipzig as part of the arrangement.
However, they would consider paying an additional compensation fee to bring Keita to Anfield in light of Philippe Coutinho's transfer to Barcelona.
Leipzig are not keen to let Keita go now at such a critical stage of their season.
They remain in the Europa League and are pushing for Champions League qualification. Liverpool understand their reservations and ultimately are prepared to wait until July 1 when the Guinea international midfielder is officially due to join.
Liverpool have ruled out a move for Leicester City's Riyad Mahrez and while they admire Thomas Lemar at Monaco, his club are reluctant to sell in January, and no offer has been made.
Jurgen Klopp is prepared to go with the squad he has should targets fail to become available.
