The former Arsenal defender sees comparisons between Sanogo and Adebayor when he played under Arsene Wenger, although Keown admits the Spurs forward has not fulfilled his potential.
In that regard, however, the 21-year-old Arsenal man could become more successful than the Togolese forward.
"When I first saw Sanogo play, I thought he was so far from being an Arsenal player. But when Wenger sees something in a player he often doesn’t give up," the former Arsenal defender said in a 'Tackle Keown' session on the Daily Mail website.
"I don’t like to talk about players as a project but Wenger will be thinking: ‘How far can I take this lad?’
"In a way it’s not a dissimilar situation to when Emmanuel Adebayor arrived. He was raw but athletic and Wenger moulded him in to a top player, almost overnight. Adebayor hasn’t fulfilled his potential but Sanogo could be a player in the same vein."
The Tottenham striker has frustrated fans this season, while Arsenal's Sanogo scored against Borussia Dortmund in the Champions League last night.
