In early 2006 Oliva was appointed at the first team, following the sacking of Chuchi Cos, being in charge for five games – three wins, one draw and only one loss, against FC Barcelona – before being dismissed himself by eccentric club chairman Dmitry Pietrman. Alavés would finally suffer relegation from La Liga.
Returned to the third level with CE L'Hospitalet, Oliva led the Catalans to the fourth position in the regular season and the subsequent promotion playoffs, which ended without success. After a few months in Greece with Aris Thessaloniki FC, he returned to his country and its division three, being one of three managers for Villarreal CF B as the Valencian finished in midtable.
In the 2008–09 season Oliva returned to the top flight, acting as assistant for both Manuel Zambrano and his successor, Lucas Alcaraz, as Recreativo de Huelva finally ranked in the 20th and last position. In the following campaign he was fired midway through the second division campaign at UD Salamanca, but the Castile and León team finally managed to stay afloat.
On 6 December 2010 Oliva joined Gimnàstic de Tarragona in the second level, replacing fired Luis César Sampedro as the team ranked in last position. He managed to finally lead it out of the relegation zone, notably with a 3–1 home win against eventual champions Real Betis on 15 May 2011.
