[6][7][8] In January 1970, a month before his 20th birthday, he joined Arsenal for £100,000, a club record fee at the time.

The acquisition of Marinello also marked the first time that Arsenal had paid a six-figure sum for a player.

[9][8] Next month on the fifth of February he appeared as a guest on the weekly pop show Top of the pops and on February 21st he reviewed the singles of the week in the music magazine Melody Maker (instant karma by John Lennon was single of the week) However, a combination of a newly adopted 'celebrity party lifestyle' and a knee injury led to a dip in his footballing form[7][8] and meant that he was not a regular in the team: he was not part of the squad for the final of Arsenal's Inter-Cities Fairs Cup triumph of 1970,[8] but he contributed four appearances during the run, including the semi-final first leg against Ajax.

[12] He next played for Portsmouth followed by Motherwell,[13] Canberra City, Fulham, Phoenix Inferno, Heart of Midlothian[14] and Partick Thistle.

[7][8] Though he retired a wealthy man, a failed business venture left him bankrupt in 1994.
