The invitation was issued by the Chief Commissioner of the Uganda Revenue Authority (URA), John Musinguzi, while welcoming TRA SC that returned to Dar es Salaam from Morogoro, where this year's SHIMMUTA Games took place.
Commissioner Musinguzi congratulated the champions and urged them to continue maintaining good co-operation at work and in sports they participate in.
He said he was aware that success in sports would also help in boosting the country's development through the daily duties they do.
"I see five cups in front of me, I invite you to come to Uganda to either play a friendly match or they will come here (Tanzania), I promise you also in Uganda we have a strong football team, I am not sure in other sports, but let's start with football first,'' Musinguzi revealed.
The Chief Commissioner of the Tanzania Revenue Authority (TRA), Alphayo Kidata, commended his players for continuing their dominance in the competition and said they had given the institution great respect.
Kidata told them to make sure they continue to do well, he has set aside a portion of money for the renovation of the stadium where they practice.
The official directed that by June next year, the stadium should be completed and ready for use.
"I want the stadium to be renovated and modernized, we can't train in bad venues and then go and compete in good stadiums, we will fail," Kidata said.
The team's spokesman, George Gassaya, thanked the TRA leadership for cooperating with the outfit from the preparations until they took part in the tournament.
Gassaya said the focus and dedication of the team's players was another factor that led to their successful defense of the tournament's top honour.
"We had a lot of practice, you know this team is made up of players from all over Tanzania, and football is not our official job, but we had a good time to prepare and we finally emerged champions,'' Gassaya revealed.
TRA SC emerged this year's SHIMMUTA Games' soccer champion after beating Ngorongoro Conservation Authority (NCCA) side 1-0.
