Amazingly only 34, according to reports which would have made him 14 when he made his professional debut, The Yak is currently playing for Coventry City and says he still keeps an eye on Everton.
Yakubu added that it may take a few weeks for Gana to regain his pre-AFCON form and earn his place back in the first team for Everton.
Yakubu said: “It is pleasing to see and, for me, he is the signing of the season.
“He has everything – energy, pace and he supports the team at both ends of the pitch.
“The supporters have taken to him and I’m sure they will enjoy him even more and more as time goes on. I think next season he will be even better.
“It is quite difficult to come back from an Africa Cup of Nations in the middle of the season.
“It’s a different kind of football and you have to change your mentality for the tournament.
“It can be difficult in Africa – a lot of the pitches aren’t great which makes it tough.
“I found it took two or three weeks to get back up to full speed after returning, which I think is the case for a lot of players.”
