Speaking to Standard Sports, Muhambe said Ebwali played against strong players in the regional finals and proved their prowess by winning the national title on an unbeaten record, scoring 17 goals and conceding only two goals.
"This win is one of a kind because we defeated everyone to be crowned champions. We did not win the title by appeals because it was fair at the nationals compared with regionals," said Muhambe.
Ebwali thrashed Bute Boys 7-0 and Mbooni 5-1 in the group stage before sealing their semis spot with a 3-1 win over Highway Secondary of Nairobi.
The Lwanda Sub-County school knocked out Kabarnet 1-0 before winning their maiden national gong with another 1-0 win over Highway.
It is with the same momentum that Muhambe has said Ebwali will approach the East Africa secondary school games that begin today in Arusha, Tanzania.
Ebwali are in pool B that also has 12-time champions St. Mary's Kitende, Budo Secondary School from Uganda, St Patrick's from Tanzania and Katoro Secondary School, also from Tanzania.
Muhambe said even as underdogs, fans should not rule them out that fast.
"It is unfortunate that many people are already predicting and favouring the Ugandans relying on past history. In my life, I have never feared an opponent because football is just football, the best team will be known on the pitch," added the former Olbolsat coach.
"Remember we went to the nationals last week without having trained for a single day after the appeal verdict was issued on the eve of the games. This shows how prepared the team is and we are going to take the same spirit to Tanzania."
Ebwali will be banking on their captain Brian Lumgafwa and attacking midfielder Derrick Opayo for glory. Both were instrumental during the nationals. The Kenyans will play Budo in their second match on Saturday.
National runner-up Highway Secondary will headline Group A that also has Kibuli Secondary School and St Andrew's Kaggwa, all from Uganda, ES Gasiza from Rwanda and Kwira Coal Mines Secondary School from Tanzania.
Highway will play Kwira Coal Mines in their opening match tomorrow before facing Kaggwa in their second match on Saturday.
In girls' football, national champions Wiyeta Girls will be seeking to reclaim the title they last won in 2017 in Gulu, Uganda.
To do that, the four-time East Africa champions have to go past Isevya Secondary from Tanzania, St Noah Girls and Amus College School, all from Uganda, in Group A.
Debutantes Dagoretti Mixed Secondary will be up against defending champions Kawempe Muslim Secondary School (Uganda), Sacred Heart Secondary School (Uganda), Rwanda's IP Mukarange and Alliance Secondary School (Tanzania) in Group B.
In rugby Sevens, six teams will battle it out in a round-robin format with Kenyan champions Koyonzo Secondary School and runner-up Butula Boys set to face off again.
With defending champions Upper Hill out of contention, Koyonzo, who reigned supreme in Nakuru, will hope to bring the title back home.
Koyonzo will face Elerai Secondary from Tanzania in their opening match on Saturday before meeting Jinja Secondary School, Hanna International and Ntare School all from Uganda and Butula.
