"There are things and there are things that I can not say otherwise I will get fined", Pogba told the British press after the Leicester match in a rare occasion he has stopped to speak with them.
Brown is intrigued by the midfielder's statement, but thinks he will let his football do the talking.
"We are following many players, Rabiot is one that has shown quality, but time will tell", the advisor said.
But Shaw has started this season brightly and Mourinho recognised the defender's improvement during a private chat with the players.
"It hasn't gone well, but you've got to remember Jose Mourinho has spent a lot of money, but the Louis van Gaal signings I have to say were really poor". We're focused on the league, so it's best to ask (Eric) Abidal, (Ramon) Planes or Pep Segura about players.

Pogba was also asked about the contrast playing for Red Devils and Les Bleus. "It is just the win that is the most important". It's also claimed that Pogba's agent Mino Raiola is keen to get the France worldwide out of Old Trafford.
Tottenham's Toby Alderweireld and Bayern Munich's Jerome Boateng were both wanted by Mourinho, but United's executive vice-chairman Ed Woodward was unable to strike a deal for either player.
Brown, who played for United over 350 times, does not think the defensive crisis is as bad as people think.
Jose Mourinho handed the England worldwide a starting spot in the Manchester United team for the visit of Leicester City at Old Trafford on Friday night.
Pogba has become the teacher in this United midfield, with summer signing Fred and academy product Andreas Pereira looking up to the Frenchman and learning from him. The latter is the heartbeat of the team, its best player, a homegrown gem who won the World Cup and lives the life of an worldwide celebrity.
