Youth career & Atromitos He was born on the Greek island of
Kos and started his career in 2001 at local team Asklipios Ko. In 2004, he moved to
Nikea-based club
Chalkidona and when Chalkidona merged with
Atromitos, he was transferred to the latter.
Panathinaikos On 24 August 2009, Marinos signed a contract with
Panathinaikos as a replacement for
Bryce Moon, who was sent away on loan to
PAOK the same year. It was agreed that Atromitos would receive a fee of . and made his league debut on 13 September 2009 in an away game against
Panthrakikos, playing a full 90 minutes. He was a member of the Panathinaikos team that won
the double in 2010.
Charleroi On 14 July 2013 Marinos signed a two-year contract for an undisclosed fee with the Belgian club
Charleroi. He made his debut with the club on 17 August 2013 in a 1–2 home loss against
Kortrijk and scored his first goal on 29 November 2014 in a 2–3 away win against
Westerlo. On 12 August 2015, after a remarkable year with the club, Marinos extended his contract till the summer 2018. He returned to the squad after three months playing as a starter in a 3–2 home loss against
Waasland-Beveren. On 21 April 2016, almost at the end of the
2015–16 season, Frédéric Borlée, doctor of the club, summarises the doctoral report:
" He suffers from the disease of Haglund . Basically, it has a bony outgrowth at the back of the calcaneus (heel) which caused partial rupture of the Achilles tendon. The operation is necessary." Furthermore,
"...the Greek midfielder had several injuries in the last few months and his return to the squad should not occur before 4–5 months", the doctor concluded. Marinos will therefore miss the summer preparation as well as the beginning of
2016–17 season. After a very difficult period for the defender marred by injury (252 days to be exact), on 17 December 2016, he returned to the squad as a starter in a 2–0 home win against
Royal Excel Mouscron. On 19 February 2017, in a 1–1 away draw against rivals
K.R.C. Genk, he scored his first goal in the season as a substitute, helping his club to climb in the 5th position of the League. He started the
2017–18 season as a starter. On 1 December 2017, in a home game draw against rivals
K.V. Oostende reached 100
League appearances with the club's jersey. On 28 March 2018, during an impressive season, Marinos renew his contract with
Charleroi for three years (plus an optional year) for an undisclosed fee. ==International career==
