Born in Bafoussam, West Region, Webó started his professional career in Uruguay, playing three years with Club Nacional de Football, winning two Primera División titles – although he only was an important first-team member in his third season – and becoming top scorer of the 2002 edition of the Copa Sudamericana.

[4] In the summer of 2003, Webó returned to Osasuna, for whom he scored six goals in the 2005–06 campaign,[5] being instrumental in the Navarrese side's fourth La Liga place and qualification for the UEFA Champions League,[6] although they would ultimately be ousted by Hamburger SV prior to the group stage.

[7] Webó's 2006–07 pre-season was hampered after he was forced to undergo treatment for malaria,[8] but he went on to produce similar numbers in the league, adding two goals in nine games in the team's semi-final run in the UEFA Cup, including the match's only in a home tie against Rangers.

Following Dani Güiza's departure, Webó's importance increased, and he totalled 22 goals the following three seasons,[11][12] netting six in 2009–10[5] as the Balearic Islands team finished fifth and qualified for the Europa League (later revoked).

[13] In the 2011 off-season, after scoring 11 times during the campaign,[14][15][16] with Mallorca narrowly avoiding relegation,[17] Webó announced he would sign a new contract only if he was offered a three-year extension.

Webó scored in a 3–1 friendly loss against Portugal on 1 June 2010,[36] and started in the first two games at that year's FIFA World Cup in South Africa (both ending in defeat), with the player not managing to find the net.
