Lucas David Pratto (Spanish pronunciation: [ˈlukas daˈβið ˈpɾato]; born 4 June 1988) is an Argentine professional footballer who plays as a striker for Paraguayan Primera División club Olimpia.

[1][2] His first professional club was Boca Juniors, by whom he was loaned to Argentine sides Tigre and Unión, Norway's Lyn and Chile's Universidad Católica.

His performances for the latter prompted a transfer to Italian club Genoa, shortly after which he joined Vélez Sarsfield, first on loan and then permanently, when he was elected Argentina's 2014 Footballer of the Year.

[3] He then moved to Brazil, playing for Atlético Mineiro and São Paulo, before returning to Argentina for River Plate in 2018, with whom he won the Copa Libertadores title later that year.

[5] Product of Defensores de Cambaceres lower divisions, Pratto joined Argentine club Boca Juniors in 2006, after a recommendation by Martín Palermo.

Leandro Lázzaro's departure to Estudiantes,[8] however, allowed Pratto to break into the starting eleven and challenge the possibility of being the team's first choice striker.

[9] On 2 August 2008, Pratto joined Norway's Lyn Fotball on a free loan from Boca, after being recommended by the scout Terje Liverød who helped with the negotiations.

[6] After once again not being considered at the La Bombonera squad, Pratto had another brief loan spell in the first half of 2010, this time at Unión de Santa Fe in the Primera B Nacional.

On 29 June 2010 Pratto joined Chile's Universidad Católica on loan from Boca, this time as part of Gary Medel's contract extension negotiation.

[13] At first, Lucas was heavily criticized for his bad shape at the Las Condes-based team, but key goals in the end of the season against Universidad de Chile[14] and Cobreloa[15] helped Católica achieve their 10th Campeonato Nacional title.

[20] He officially debuted as a starter during Genoa's first 2011–12 Coppa Italia game against Nocerina in a 4–3 home win,[21][22] in which he scored his side's second goal after an assist by Kévin Constant.

[27] Since that time Lucas failed to play the rest of season, being relegated to the bench by the team's next coaches (Pasquale Marino, the same Malesani and Luigi De Canio).

On 7 February 2012 it was reported that Pratto had joined Vélez Sarsfield in a season-long loan deal, with the option to be fully signed by the Argentine club.

[29][30] After a decent first season with the Liniers side, in which he played 20 times and scored 4 goals, Lucas became a starter during Vélez's 2012 Torneo Inicial championship-winning campaign.

[36] In the second leg of the Campeonato Mineiro semifinals against fierce rivals Cruzeiro, Pratto managed to score a brace with two assists by Guilherme, one of the goals an impressive volley, and helped his team make a 2–1 comeback after trailing in half-time.

[38][39] In July 2015, Pratto became Atlético's highest-ever foreign goalscorer and scored his first-ever hat-trick, with all three goals coming in the first half of a 3–1 home win against São Paulo.

[53] On 9 May, in a 3–0 league defeat to Ajax, Pratto suffered a fracture in his right ankle when challenging for the ball; he underwent surgery on the same day, with an expected recovery time of four to six months.

Lucas has an interest on rock and roll, being a fan of AC/DC, Foo Fighters, Kiss and Argentine band La Renga, of whom he also has a tattoo.
