Pogba captained United - a move regarded as an olive branch from Mourinho who also praised his performance - but hinted at problems with the manager by also failing to mention him when praising fans and team-mates.
Prior to the transfer window slamming shut on Thursday evening, there had been a few weeks of speculation that Pogba even wanted to leave Old Trafford for a second time, with his agent Mino Raiola seemingly trying to negotiate a £100m move to Spanish giants Barcelona.
The Dutchman's honours in Manchester include four Premier League titles- three consecutive between 2006 and 2009- and memorably saved the decisive penalty from Nicolas Anelka to win the Champions League for Manchester United over Chelsea in Moscow in 2008.
For France, Pogba was paired with N'Golo Kante in midfield and the Chelsea man's aggression and energy allowed Pogba to express himself on the ball.
"What do you mean being the real Pogba?" he asked.
Pogba calmly slotted the ball into the top corner
"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. The team is focused on LaLiga, so it's better to ask those responsible for transfers about those topics".
Paul Pogba said he needs to be happy to perform at his best for Manchester United, adding that he would be fined if he spoke his true feelings.
"There are things, and there are things that I can not say, otherwise I will get fined", Pogba said.
"Pogba will be staying", Brown told Starsport. No, I just have to be myself and do what I know, do what I can do and do what I know to do. There are problems, I was surprised to see him play [against Leicester].
"And wearing this armband, it's even more [special] because of the past, because of the players that played here, the people that have been wearing this".
