RIO DE JANEIRO, Dec. 26 (Xinhua) -- Former Palmeiras, Cruzeiro and Santos midfielder Robinho Signorini has announced his retirement after a professional career spanning two decades.

The 38-year-old's contract with Brazilian Serie C side Brusque ended this month, and he declined offers to continue playing to accept an assistant coaching role with Nautico, which will compete in Serie B next year.

"I am putting a full stop to my journey as a professional athlete. However, I will continue in the world of football, now from outside the four lines," he said in a social media post.

Robinho's career highlights include a Brazilian Serie A title and a Copa do Brasil trophy with Palmeiras, and two Copa do Brasil triumphs with Cruzeiro.

His career also included spells at Varginha, Mogi Mirim, Avai, Coritiba and Paysandu.

"I thank all the clubs, teammates, coaches, fans, support staff, directors and agents who were part of my story as a player. Without you, I would not have achieved my collective and individual goals," Robinho added. ■
