Before Sebastien Migne's appointment, the former AFC Leopards custodian was working as an understudy to Boniface Oluoch. He rarely started, unless the latter was nursing an injury.
However, the situation changed for the better when the Frenchman arrived, and Matasi's performances quickly ensured he became established as the team's No. 1.
Matasi made daring saves in the 1-0 win against Ghana at home during the Afcon qualifiers and the 0-0 draw away to Ethiopia.
During the Nations Cup in Egypt, he managed to save a Sadio Mane penalty in the 3-0 defeat by Senegal, and made a series of fine stops as Kenya beat Tanzania 3-2.
The youngster was drafted into the side by Migne ahead of the Africa Cup of Nations, playing two friendlies ahead of the tournament and then all three group-stage games.
After the injury to defender Joash Onyango, many expected to see David Owino take his place, but surprisingly, it was the youngster who was given the nod.
Okumu delivered a series of composed displays, making several key blocks against some of Africa's finest attackers.
At just 22, he commanded the back-line well alongside Musa Mohammed and won the hearts of many with his showings.
Eric OumaCommonly referred to as ‘Marcelo’, the youngster came to the rescue of Migne when called upon. During the Afcon qualifiers, he was overlooked, but when he got the chance, he took it emphatically.
A dedicated player who gave 100% in the matches he played regardless of the position, Ouma never let the coach down and was an eye-catching contributor for Kenya in wide areas.
Against Malawi, it was his cross from which Francis Kahata benefited to give Kenya a 1-0 win. Ouma was solid against Ghana away, and he helped stabilize the team in the Afcon, especially against Algeria as elder players wilted.
- Goal Kenya.
The former Mathare United attacker was instrumental in the team's qualification to the Afcon. He was involved in the four goals scored by the Harambee Stars during the campaign.
It was from his passes the team scored and many expected him to shine at the Afcon in Egypt.
Just like the majority of the team, Johanna, who plays for who plays for IF Brommapojkarna in Sweden, flopped in the opening game against Algeria but came off the bench against Tanzania to create the winner for the Harambee Stars.
While Johanna struggled against Senegal in the 3-0 defeat, he will surely be a key man for the national side moving forward.
The seasonal striker never disappointed for Kenya, and when he was available for selection, he did the job. The towering Olunga forced an own goal against Ghana's Black Stars in the 1-0 win at home, and later scored against Ethiopia in the 3-0 victory.
At the Afcon, the former Gor Mahia striker rose for the occasion to help Kenya win her second game in the history of the competition.
Olunga scored a brace against Tanzania in the 3-2 win and consistently forced opposition goalkeepers to make saves during the campaign.
Even though some of his teammates failed to live up to the expectations, Olunga proved that he ought to be considered among the continent's pre-eminent forward.
