There are reports that Galatasaray are only offering half the €10m asking price for Lazio midfielder Daichi Kamada.
According to Calciomercato.it, the proposal from the Turkish side is currently at €5m, just half what the Aquile are asking for.
If the two clubs do not move towards each other significantly, then Galatasaray could veer on to different targets, such as former Inter midfielder Christian Eriksen of Manchester United.
The Japan international eventually signed for Lazio as a free agent over the summer when his contract with Eintracht Frankfurt was allowed to run down.
He had been in talks with other clubs, including Milan, Inter and Roma, before opting for the Biancocelesti.
However, the 27-year-old failed to make much of an impression at the Stadio Olimpico and dropped down the pecking order under coach Maurizio Sarri.
He made 22 competitive appearances this season, increasingly only from the bench.
Kamada contributed one goal and one assist, both in Serie A.
