Things did not go to plan for Zaha at Old Trafford, though, as he quickly ended up back at Palace while switching international allegiance to the Ivory Coast.
Now 25 years of age, he has rebuilt his game and reputation back in familiar surroundings and is considered to be deserving of high-profile transfer after snubbing fresh terms at Selhurst Park.
Former Palace winger Salako told Love Sport Radio: “I think he went off to Man United too early.
“He came back and he’s been absolutely sensational. It is his home, he is comfortable and he knows everyone.
“I think turning down this contract in a massive indication that he’s got some interest elsewhere and could be ready to move elsewhere.”
Spurs have been linked with Zaha for some time, with the development of a local rival being closely monitored, and Salako believes a move across London would make a lot of sense.
He added: “I think he brings something different to Spurs.
“He wouldn’t necessarily be a starter but I think once he goes and trains and [Mauricio] Pochettino gets hold of him and they work with him and explain to him…I think he understands that side of the game and going and defending.
“I believe that Zaha’s physicality, strength, pace and ability on the ball is just phenomenal.”
Zaha enjoyed the most productive season of his career to date in 2017-18, making 29 Premier League appearances and netting nine goals.
He also provided three assists, with his efforts contributing significantly to Palace recovering from a slow start to steer a course to safety under Roy Hodgson.
