[5] After another half-season in San Sebastián, Jankauskas was loaned to Benfica for the remainder of the 2001–02 season, though the Lisbon side initially wanted his strike partner Darko Kovačević.

[8] He caused controversy by declaring to El Diario Vasco that Benfica was like a religion before signing for Porto; he clarified that he was talking about their level of support and not his intention to stay at the Estádio da Luz.

[14] After the departure of Mourinho, Jankauskas fell out of favour in Porto and joined Nice on loan,[15] but he failed to settle in France, and eventually signed for Scottish Premier League club Heart of Midlothian – via FBK Kaunas – in 2005.

[17][18] The following campaign was less successful for him, as injuries and indifferent form limited his appearances; after his Kaunas and Hearts contracts expired in June 2007,[19] he signed with Cyprus's AEK Larnaca.

[20] He terminated his contract after only a few months, moving to Latvia's Skonto Riga in the summer after claiming he wanted to play closer to his homeland.

[26] Jankauskas was an important part of the Lithuanian national side since 1991 when, at the age of just 16, he helped the country to the 1991 Baltic Cup, playing the last 30 minutes of the 4–1 final win against Estonia.

On 12 January 2016, after a brief spell at club level with FK Trakai, Jankauskas replaced Igoris Pankratjevas at the helm of Lithuania.
