Ricketts, who made his Arsenal debut against Manchester United in the League Cup at the age of 18, is all set to show his skills in the upcoming football season and take Dempo to the next level.
The striker recently gave a promising performance by netting twice in an eight-a-side match during his first session with the Panjim city-based club at the University ground, Taleigao.
Ricketts played for Tottenham before moving to Canada, Hungary, Moldova, Germany, Republic of Ireland, and now India.
