"My desire [to coach] remains intact and I reckon I could do it in Spain," said Maradona.
"After the 2010 World Cup, I received two or three interesting proposals. But they didn't suit me. I thanked [the clubs] and said the time wasn't right. But now that the summer has passed, I'm approaching things differently."
Maradona, 50, took charge of Argentina at last year's FIFA World Cup in South Africa but saw them thrashed 4-0 by Germany in the quarter-finals.
The Argentinian Football Association (AFA) subsequently decided not to prolong his contract.
At the beginning of January he claimed to have received an offer to coach an English club, which at the time was rumoured to be Fulham.
