Liverpool will reportedly have to contest interest from German champions Borussia Dortmund if the Reds hope to sign South Korea international Son Heung-Min from Hamburg.
Son's impressive start to the season, during which he has scored four goals in seven Bundesliga appearances, has seen him linked with a move to Liverpool during the January transfer window.
Liverpool, however, will not have a free run at Son, with reports in Germany claiming Dortmund are also keen for the 20-year-old forward to boost Jurgen Klopp's attacking options.
According to Bild, Liverpool are considering an offer for Son in the region of €10.5 million, although this it not expected to tempt Hamburg to allow the youngster to move to Anfield.
While the potential fee poses a problem for Liverpool, so does the apparent interest from Dortmund, who are reported to have Son on a list of January transfer targets.
But the lure of a move to Liverpool or Dortmund could prove to be too much for Son, who continues to grow in stature for both club and country.
