The 29-year-old, who also took the award in 1997, 1998, 2000 and 2001, was a UEFA Champions League winner with FC Porto last May, having won the UEFA Cup with the Portuguese club the previous season. He was the first Lithuanian player to lift either trophy.
Since September, Jankauskas has been playing with French Ligue 1 team OGC Nice on a season-long loan from Porto. Meanwhile, he has shown his quality in the FIFA World Cup qualifiers, scoring one goal against Belgium and two against San Marino.
Jankauskas won the prize with 362 points, putting last year's winner - FC Krylya Sovetov Samara's Robertas Poskus (216 points) - into second place with PFC CSKA Moskva defender Deividas Semberas (207) third.
