Junior Gunnar Putera Eldstål (born 16 September 1991) is a Malaysian professional footballer who plays as a centre-back for Thai League 1 club Bangkok United and the Malaysia national team.

Sarawak officially booked their spot in the quarterfinals of the 2013 Malaysia Cup as they smashed in six goals against Perak to secure an impeccable 6–1 win.

[9] On 11 November 2014, Eldstål announced that he had signed a contract with one of the top teams in Southeast Asia, Johor Darul Ta'zim FC under coach Bojan, playing in the Malaysia Super League,[10] until 2015.

[11] On his move, he was promptly inserted into the starting eleven playing as a centre back for the first pre-season matches against Johor Darul Ta'zim II, PKNS and Penang FA.

Eldstål would also like to break into the Malaysia national football team, unfortunately being unselected to Dollah Salleh's squad for the 2014 AFF Suzuki Cup.

Eldstål was then played in midfield again alongside Hariss Harun and regular defender Marcos António, where Junior scored his first-ever Super League goal of this season in the 61st-minute equaliser in a 1–1 away game over Sime Darby.

On 29 October 2018, Eldstål uploaded a video and a statement to his personal social media, confirming the end of his time in Johor Darul Ta'zim and his return to the UK.

[19] In July 2013, Eldstål was called up to join the Harimau Muda A squad for the World University Games in Kazan, but he was not allowed to be registered for the tournament due to technical issues.

Malaysia emerged as Asia Cup Champion after defeating Myanmar 2–0 at the Darul Makmur Stadium, with the match concluding with his goal in the 90th minute.

[23][24] In September 2014, Ong Kim Swee named Eldstål in his final 23-man squad for the 2014 Asian Games, playing in Group A for the tournament in Incheon, South Korea.
