Gudelj was born in Trebinje, Socialist Federal Republic of Yugoslavia. After making his professional debuts with FK Velež Mostar he moved to Spain, signing with Celta de Vigo in the second division. He scored 27 league goals in his debut season, the Galicians promoted to La Liga and the player continued to lead the scoring charts for his club the following five years.
Gudelj left Celta in 1999 as the player with most goals in its history, with almost 100 (68 in the top flight alone). He then joined neighbours SD Compostela, returning to the second level and being the best scorer in the team in both campaigns.
