Mailson Alves started his career at Brazilian outfit Sao Jose but moved to Portuguese Secunda division club Portimonense, and played his part in the club's second-spot finish in 2009-10. After surfing through a host of Brazilian clubs, the centre-back joined Tombense and helped them to a Serie D triumph.
He joined Serie C side Tupi and was an inspirational figure as his side upset Serie A's Atlético Paranaense in the Copa do Brazil in early 2015. After making 12 appearances in Chennaiyin FC's backline in 2015, when he helped them to a league triumph, Alves signed on the dotted line for the Highlanders ahead of Season 3.
