The country will feature two teams at the one-week event and the squads are led by three coaches, namely Laizer, Waziri Rajabu and Goodluck Mollel.
Laizer, who was training eight junior national team players that are based in Moshi, said he is optimistic that the country will perform well at the event.
He said he is basing his confidence on the fact that the country has many young players who have been doing well at local and international junior events which are played on hard courts.
Laizer said the DGC courts are cemented, an aspect that makes it difficult for many players, especially those from Kenya, to play.
He also said his squad comprises talented players including Victoria Ndosi, Deborah Lema and Beatrice Kimaro, who have been outstanding at international events, the recent one being the Kenya Open where they performed well.
"I am very confident our players will perform well at the event, my players have been training well and all of my players are saying the same," Laizer said.
"The other advantage on our side is that we will be playing at home where the courts are cemented, most of teams from outside the country are used to playing at clay courts," he said.
Countries that are expected to compete at the championships are Kenya, Uganda, Rwanda, Burundi, Somalia, Comoros, Eritrea, Seychelles, Sudan, Ethiopia and hosts Tanzania.
However, yesterday afternoon, Tanzania Tennis Association (TTA) president Denis Makoi said all teams, with the exception of Somalia, have arrived for the event.
"I have been informed that many teams have arrived while others are on their way, Somalia is the only country which we are not sure of its arrival and all preparations are over," he said.
The fixture for matches were expected to be out yesterday evening.
