Aronica spent his early career with
Juventus, but he was sent to
Crotone on loan. The deal became a
co-ownership deal for the 2000–01 and 2001–02 seasons for €91,000. In June 2002, Aronica returned to Juventus for an undisclosed fee but was loaned to Serie B side
Ascoli with an option to purchase. However, the next season, he moved to
Messina from Juventus, along with
Luigi Lavecchia and
Andrea Gentile, in another co-ownership deal. Aronica was valued at €1 million at that time, thus Messina purchased half for €500,000. In June 2006, Messina purchased Aronica for an undisclosed fee (approximately €240,000 to €300,000) and acquired Lavecchia and Gentile outright. However, in July 2006, he was sold to
Reggina. He was signed by Napoli on 1 September 2008, for €2,675,000, With the departure of
Maurizio Domizzi and
Erminio Rullo, Aronica was featured as a left-sided central defender or as a left-sided
wingback ahead of
Mirko Savini in the team's 3–5–2 formation, sharing the role of the team's left wingback with
Luigi Vitale. In
2010–11 season he started to play with
Paolo Cannavaro and
Hugo Campagnaro consistently. Although they played well that season, in the following season, the squad's lack of depth made it difficult to face both
2011–12 UEFA Champions League and
2011–12 Serie A, making the club slip from a third-place finish in 2010–11 to fifth place in 2011–12. In May 2012 Aronica renewed his contract (1+1 year). On 29 December 2012, he moved to
Palermo, signing a contract until 2015. His Palermo stay was, however, difficult from the very beginning, as he failed in helping his club to escape relegation and was subsequently excluded from the first team for the whole
2013–14 Serie B season, as well as the early part of 2014–15. He mutually rescinded his contract in December 2014. On 14 January 2015, he returned to
Lega Pro side Reggina. After helping the club avoid relegation, he left the team at the end of the season, and briefly joined Calcio Sicilia, before retiring from professional football in 2015. ==Coaching career==
