Denson, a highly rated midfielder, joins the team from Sporting Clube de Goa while Amoes, a central attacking midfielder comes from Ozone FC.
"Our signings over the past couple of weeks make it quite evident that we want to build a very strong team for the season," Gianluca Zambrotta, head coach of Delhi Dynamos said.
"I have heard about the ability of the two players from the management and the backroom staff and after analysing their videos and careers I am delighted to welcome them into our family. They will add depth to the squad and will surely play a huge role in the club's success in the upcoming season," he added.
Amoes added: "This is my first shot at the Indian Super League and I am really honoured to be part of the Delhi Dynamos FC team. A number of people will be watching me and I would want to prove myself at this level. I am a little nervous but I believe it will only bring the best out in me. I am really looking forward to train under Zambrotta and grow under his guidance as a player.
