Ralf Rangnick concedes RB Leipzig would not be able to match Newcastle United's reported €60 million (£52m/$86m) bid for Joelinton, although he doubts the Magpies would make such a move.
Both Leipzig and Newcastle are said to hold an interest in Hoffenheim's Brazilian striker, with reports in Germany suggesting the Premier League club are close to a record-breaking deal.
Rafael Benitez's men broke their long-standing transfer record in January as they paid Atlanta United in the region of £21m ($27m) for playmaker Miguel Almiron, who starred on his full debut against Huddersfield Town on Saturday.
