Spanish attacking midfielder Pablo Hernandez joined the Whites initially on loan from Qatari side Al-Arabi, ahead of the 2016/17 season, before penning a permanent deal in January 2017.
The vastly-experienced Hernandez came through the ranks at Valencia and arrived at Elland Road with over 130 La Liga appearances to his name and four full international caps.
His career to date has included two spells with Valencia, sandwiching a season with fellow Spanish outfit Getafe.
The 32 year-old then had a spell at Swansea, prior to moving to Al-Arabi, which also included a temporary return to his homeland with Rayo Vallecano.
Hernandez signed a one-year contract extension at the end of last season, after making 38 appearances for the Whites.
