The veteran striker has managed to score 18 goals this season and many expected him to make the cut in the squad named by coach Sebastien Migne on Thursday.
However, that was not the case as the Frenchman opted to leave him out.
“To be honest I was shocked! I have been in perfect form this season and managed to score 18 goals. If the selection was done by merit, definitely I would not have missed [out],” Wanga told Goal in an interview on Friday.
“Reports that I did not impress in the camp are not true, remember we had a game against Sofapaka in Mombasa's Mbaraki Stadium, the players who managed to attend most of the sessions are those who are based in Nairobi. I attended training only on Tuesday before leaving for Mombasa for our final league game.”
The Homeboyz striker is confident that the squad that travelled will do Kenyans proud.
“Kenya is my country and Harambee Stars is our national team; I will be happy if the team goes there and performs. It is my hope that we will do better in Egypt, I wish my fellow players all the best.”
