Dosu was the only home based player to be included in Nigeria’s 1996 Olympic team, which won gold at the tournament.
However, his career was short-lived as a result of an automobile accident.
In a recent interview, Oliseh said Dosu was one of the people who helped Mikel to attain glorious status.
He said: “Before Obi Mikel made it in football, Dosu Joseph housed Obi Mikel and fed him. I bet you all didn’t know this. He helped Obi Mikel become what he is today.
“In spite of all the help he gave Obi Mikel, please let’s ask ourselves: has Obi Mikel ever once gone to say hello to Dosu? And with all the millions you’ve made, help the guy (Dosu).”
Responding to the ex-Chelsea midfielder’s recent criticism of his coaching ability, Oliseh said “I think the kid needs help”.
Mikel had criticized Oliseh’s coaching ability on his podcast, calling him “the worst manager I played under.”
“He was bitter, jealous, and disrespectful to everyone, including the physio”, he added.
Speaking during the interview, Oliseh, who spent eight months as Super Eagles coach, after being appointed in 2015, said: “I think the kid needs help. You cannot achieve what you were not able to achieve on the pitch outside the pitch by talking on a podcast”.
While defending his coaching abilities, he mentioned his award for best coach in the Jupiler Pro League, voted by players and coaches.
He said: “I think the kid(Mikel) needs help, to be honest. There’s something I’ve not really shown much, I won the best coach for the first period of the Jupiler league, which is in the Dutch league.
“That was not voted by the press, that was voted by the players and the coaches of the league.
“I’m the only, and the first coloured man from Sub-Saharan Africa to ever win this title with a club like Fortuna Sittard, who had very average players who were able to qualify from the second division from last position to the first division, where they still are now.”
