During his spell he was loaned twice, and also appeared in three competitive games with the club, totalling 57 minutes of play between the Portuguese Cup and the Portuguese League Cup. In the 2011 summer Yero joined Gil Vicente Football Club, his maiden appearance in Primeira Liga occurring on 24 October as he came on as a late substitute in a 1–6 away loss against Sporting Clube de Portugal.
