Massa, 31, brought down the curtains on his career with the Cranes in a letter addressed to the Uganda Football Federation on Wednesday (29 March 2017).
“It is with immense pride that I announce my retirement from the national football team after representing the country for 12 years. I have had an incredible career and I am thankful for each and every moment for my time with the Uganda Cranes.
“I am proud to have played for the Cranes, scored several crucial goals for the team but most important of all, to have captained the team to their first ever Africa Cup of Nations appearance since 1978.
“The experience of representing my country at the 2017 Africa Cup of Nations in Gabon was truly memorable, while the feeling after winning three CECAFA Challenge Cup titles and becoming the all-time Nations / World Cup qualifying top scorer with 14 goals, was quite satisfying,” added Massa, who captained the Cranes at the tournament whey were pitched in Group D together with Ghana, Egypt and Mali.
Meanwhile, the Uganda football Federation (FUFA) has promised to hold a testimonial match for the retired captain at a venue and date to be confirmed.
“He was a great servant. He was such a highly respected player in Uganda Cranes” said FUFA president, Moses Magogo.
