Pogba will not link up with his United teammates until they return from their pre-season tour of the United States.
"I don't answer to your question", Mourinho told reporters at United's Los Angeles training base ahead of a friendly against AC Milan on Wednesday.
In comparison to Rojo, Maguire did not miss a single Premier League game for Leicester City, following his £17 million move from Hull City and had an outstanding summer in Russian Federation, emerging as one of England's best players in football's biggest competition.
And this could have sealed his fate at Manchester United.
"So I think it was the ideal environment for him".
"He is a top player, but we are not interested in him".
"I don't think he will be available to play any one of the three matches of the International Champions Cup", Mourinho said.
Manchester United have reportedly opened talks to sign Eintracht Frankfurt winger Ante Rebic. So against Leicester and Brighton the situation is not awesome for us.
Paul Scholes is arguably one of the greatest English midfielders to have ever graced the game - but Sir Alex Ferguson wasn't so sure when he first saw him.
Marcos Rojo is one player who may not join up with Mourinho's squad in the US.
However, the pre-season tour is still in its early stages and the Portuguese boss could change his mind if the forward proves his worth especially in terms of output.
