Jean Deza

Žilina

In August 2011, he joined Slovak club Žilina on a four-year contract. His debut came on 27 August 2011 in the Corgoň Liga match against Dukla Banská Bystrica, entering in as a substitute in place of Roman Gergel. Jean Deza was linked to Argentinian club Boca Juniors, and Swiss Basel before joining his present club.

Montpellier

In August 2013, he joined French club Montpellier on loan for one year.

Levski Sofia

In May 2016, Deza joined Bulgarian club Levski Sofia on a two-year deal. On 7 February 2017, he terminated his contract with the club after not showing up at Levski's winter training camp. Because of that, the player and the club had resolved the argument with the help of FIFA.

After some impressive performances for Montpellier, Jean Deza was called up for a friendly against England for England's World Cup 2014 warm up games. He started the game, putting in an impressive performance before later being substituted in the second half. The main highlight from Peru was when Deza tried to chip England's Joe Hart from 35 yards, only going over by a little.
