Wallace Karia, TFF president, issued the call shortly after welcoming the country's U-20 women soccer squad, Tanzanite, which won the inaugural U-20 Women Championship which was held in Port Elizabeth, South Africa last week.
The team arrived at the Julius Nyerere International Airport in Dar es Salaam on Monday night from South Africa.
Tanzanite posted 2-1 victory over Zambia in an entertaining final that took place at the Wolfson Stadium last weekend to win the trophy.
The victory, in the process, saw Tanzania turn into the first guest nation to win a COSAFA competition.
Karia disclosed soccer enthusiasts in the country should back efforts by TFF to raise the standard of women soccer at the domestic level with a view to seeing to it the country wins more trophies in high profile tournaments.
"I thank god He has helped us fulfil our plans. Investment in soccer development plans from grassroots is the most important aspect," he disclosed.
"A section of the players in this team, which took part in the COSAFA U-20 Women Championship, were picked from such regions like Ruvuma and Mwanza, they went on to make wonders, all I want is people should back TFF's efforts to develop women soccer."
"We will obviously win more trophies if we will work together. We have won a sixth silverware since this TFF leadership took office."
Tanzanite lifted inaugural COSAFA Women’s Under-20 Championship with a hard-fought 2-1 victory over luckless Zambia in the final.
Zambia had triumphed by the same score line in their meeting in the group stages, but it was roles reversed as the East Africans this time came out on top.
After a cagey beginning, Tanzania took the lead when Opa Sanga swept home a cross from the left-wing, her third goal of the tournament.
Tanzania had a few opportunities to add to that lead, but were pegged back 10 minutes into the second period when Loveness Malunga netted a wonderful equalizer.
She picked up the ball on the edge of the box and rifled home a shot to bring the score level.
It looked as though the game would be headed for penalties before Protasia Mbunda scored a stunning winner with five minutes remaining.
The ball was cleared to her 30 yards from goal and she crashed a shot into the net from that distance, beating Zambia goalkeeper Anna Mukumbuta with her pace and power.
That sparked wild scenes of celebration and Tanzania were able to hold on for the win and lift the trophy.
Maylan Mulenga from Zambia won the Golden Boot award with five goals, while her compatriot Cynthia Shonga was named Goalkeeper of the Tournament.
The Player of the Tournament prize went to Tanzanite’s striker, Enekia Kasonga, nicknamed Lunyamila, who was a star throughout.
