Susic, 23, started his career with the likes of Vise, Genk and Standard Liege having emigrated from Sarajevo to Belgium at an early age, but moved to Croatia in 2012 with Hajduk Split.
The midfielder was a part of Bosnia's World Cup squad in 2014, before hitting three goals and seven assists for Hajduk last season as he continued to develop and become a hot property over in Croatia.
Now, Susic may look to leave Croatia and make his big move to a top club in Europe, with Alfredo Pedulla of SportItalia reporting that a move to Inter Milan broke down over the summer, and Sampdoria are looking to lure him to Italy.
However, Pedulla also states that Liverpool and West Ham are ready to battle over Susic's signature ahead of the January transfer window, with both teams seemingly impressed with his play in Croatia.
West Ham are currently missing star playmakers Dimitri Payet and Manuel Lanzini, so could look to bring Susic in to compete behind them, whilst Liverpool boss Jurgen Klopp will be hoping to mould his own Reds side having taken over from Brendan Rodgers back in October.
One interesting sub-plot is that West Ham boss Slaven Bilic is something of a Hajduk legend. With two spells there as a player and one as a manager, Bilic is still loved at Hajduk, and that influence could play an interesting part in any battle for Susic's signature, with the midfielder no doubt aware of his exploits as a player and as a manager too.
