|Full name||José Leonardo Nunes Alves S. Jardim|
|Date of birth||1 August 1974|
|Place of birth||Barcelona, Venezuela|
Born in Barcelona, Anzoátegui, Venezuela, to Portuguese parents who had settled in the country, Jardim returned to Portugal at a very young age, relocating to the island of Madeira. In 2001, aged only 27, he started his manager career, acting as assistant to local A.D. Camacha for two years.
Subsequently Jardim was promoted to head coach at the third division side, moving to G.D. Chaves in the same category midway through the 2007–08 campaign and leading the northerners to promotion to the second level in his only full season.
In the 2009 summer he was appointed at S.C. Beira-Mar, achieving another promotion, this time to the top division. Jardim stepped down midway through the following season due to a string of bad results, even though the Aveiro team finally managed to retain its division status.
In May 2011, Jardim replaced Sporting Clube de Portugal-bound Domingos Paciência at the helm of S.C. Braga. He led the Minho club to the third position in his first and only season – posting a record of 15 consecutive league wins in the process - but left after a run-in with the club's president.
On 5 June 2012 Jardim agreed to join Greek club Olympiacos F.C. on a two-year contract, replacing Ernesto Valverde. He was controversially relieved of his duties on 19 January of the following year, even though the club led the league by ten points.
Jardim returned to the country of his parents in the 2013 summer, penning a two-year contract with Sporting. Leading a team full of youngsters developed at the club's youth system, he coached the Lisbon giants to the second position in his debut campaign, with 25 points and 18 goals more than the previous season.
