Nicolás Martinez (born 25 September 1987), known simply as Nico, is an Argentine professional footballer who last played as a midfielder for Greek Super League 2 club Apollon Smyrnis.

AEK will consider making a bid after the end of the season and the possibility of completing this transfer is highly likely as the two clubs share an amicable relationship.

Branco Milovanovic, AEK's technical director, is in contact with Martinez's agent and it is likely that an offer to land Panetolikos attacking midfielder is on the cards.

On 31 August 2016, in the last day of the summer transfer window, Western Sydney Wanderers have reportedly come to terms with 28-year-old Argentinian attacking midfielder and signed him on a long season loan from Greek Super League club Olympiakos.

As part of the loan deal with Western Sydney sources say that out of his current wages of $563,000 a season, the Wanderers have agreed to pay about $266,000 while Olympiakos will foot the remainder.

On 6 November 2016, he scored the fastest goal in Wanderers Hyundai A-League history to put the visitors in front inside the first minute, in a 2–2 away draw against Perth Glory.

[11] On 31 August 2017, he signed a year contract for Cypriot First Division club Apollon Limassol on a long season loan from Olympiakos.

On 27 August 2018, newly promoted Aris has taken out-of-favour Argentinian midfielder Martinez as a free transfer from Olympiacos by signing a year contract for an undisclosed fee.
