Dady's first match in the top level was on 14 January 2006, in a 0–1 home loss against Sporting where he came on as 78th-minute substitute.[1] After an uneventful first half-season he was a key attacking figure in 2006–07 campaign, scoring 12 goals as Belenenses finished fifth and qualified for the UEFA Cup.[2]
In August 2007, Dady signed with La Liga club CA Osasuna.[3][4] Not an undisputed starter in his first season, he still finished as the Navarrese's top scorer, helping it barely avoid relegation;[5] in the following two campaigns he featured even less regularly, due to physical problems – which included the extraction of a benign tumor in his femur[6]– and the resurrection of veteran player Walter Pandiani.[citation needed]
