Arsenal, Liverpool and Borussia Dortmund are reportedly locked in a battle for Olympiacos striker Kostas Mitroglou.
The 25-year-old, who joined the Piraeus-based club from Borussia Monchengladbach two years ago, has blasted 12 goals in nine games in this season's Greek Super League, helping his team to the top of the table.
According to the Daily Star, Gunners boss Arsene Wenger is keen to give Olivier Giroud some competition up front, whereas Brendan Rodgers wants to add depth to his attack, currently spearheaded by Luis Suarez and Daniel Sturridge.
Meanwhile, Die Borussen coach Jurgen Klopp is searching for a replacement for Robert Lewandowski, who will leave when his contract expires at the end of the season.
Mitroglou, who has 26 caps for Greece, is reportedly valued at around £7m.
