 He made his official debut on 16 August, rescuing a point at home against C.S.Marítimo for the season's opener (1–1); during the team's victorious campaign he served almost exclusively as backup to Óscar Cardozo and Javier Saviola, but made the most of his minutes, for instance scoring twice in a 4–2 win at Associação Naval 1º de Maio on 5 April 2010 and adding another brace in another away triumph (3–2 against Académica de Coimbra).Weldon only appeared in eight official matches in 2010–11, four in the league, totalling less than 100 minutes overall.
