That is according to ESPN FC pundit and former Major League Soccer star Alejandro Moreno.
Sancho has emerged as a £100million target for Manchester United this summer.
Paris Saint-Germain are also said to be keen on the England teenage sensation.
Sancho has enjoyed a fine first full season in the first team at Borussia Dortmund.
The 18-year-old has started 18 Bundesliga matches and five Champions League ties, scoring nine goals and assisting another nine.
But Moreno believes Sancho would not get into the United team ahead of the likes of Marcus Rashford and Anthony Martial.
Martial has recently been handed a new contract, with Rashford also in talks over an extension at Old Trafford.
The pundit believes Sancho is better off staying at Dortmund for the time being.
“I don’t quite see it to Manchester United just yet,” Moreno said.
“Let’s not forget that Manchester United just invested in Marcus Rashford and Anthony Martial and [Jesse] Lingard is there as well.
“So you’ve already put a lot of money into different assets that match very well what Jadon Sancho brings to the team.
“So therefore he may be on the move, I just don’t think it’s to Manchester United.
“If I’m him, I’m having a good time a good time in what I’m doing in Dortmund and I’m achieving success at Dortmund.
“Maybe I continue to mature at Dortmund where I know I’m going to play, I’m going to get opportunities, I continue to grow as a player.
“I don’t think it’s his time to go anywhere.”
