Born in Barcelona, Catalonia, Tonet was an unsuccessful FC Barcelona youth graduate. He played professionally for Deportivo Alavés B, CF Gavà, Real Oviedo B, Real Ávila CF, SD Compostela, CF Reus Deportiu, CF Rayo Majadahonda, CF Fuenlabrada, AD Alcorcón and CE L'Hospitalet.
In a full decade, Tonet never appeared in higher than Segunda División B.
On 4 August 2008 Tonet moved to the Scottish Premier League, signing a one-year contract with St Mirren after impressing on trial in pre-season, which included a goal against Football League Championship's Blackpool.
His league debut came against Celtic in a 0–1 away defeat, and he went on to play in the first four games, being sent off against Heart of Midlothian in another loss. However, after suffering a foot injury from which he never fully recovered, he was deemed surplus to requirements early in the following year, and released by manager Gus MacPherson at the season's end.
Return to Spain
After being released by Saints in the summer of 2009, Tonet returned to his country, joining lowly Villajoyosa CF in the third level. After the Valencian club's relegation he stayed in that category, signing a one-year deal with CD La Muela in Zaragoza, Aragon, and meeting the same fate.
Tonet's younger brother, Andreu, is also a professional footballer. Groomed also at Barcelona he appeared in La Liga for Sporting de Gijón, albeit with little impact, and played abroad most notably in Poland.
