Mourinho warned last weekend that a "difficult season" could lie ahead if they failed to strengthen the squad before the deadline, but an inflated market has made the challenge of improving defensively an even tougher ask.
"So for me it's a big season for Paul Pogba, it's a good move, let's see how Paul Pogba gets on tonight".
"My view is that first of all is hard for me to believe we finished second when I listen, when I read, not much but sometimes I do, it is hard to believe that we finished second because you [the media] are capable of making people that finish second look like they were relegated, and people who win nothing, finish below us, and you make them look like serial winners", Mourinho said.
He went on to repeat his sentiments that United are in for a tough season, after they overcame opponents who spent more cash in the summer transfer market.

"We have to prepare for this season with good possibilities". Forget the name, forget the history, forget the shirts, every team is a good team and every match is hard'.
'But I find myself in the beginning of the Premier League, with the market closed, I find myself in a situation that I thought I was not going to be in, but I think it's the last time I speak about it.
In another dig at the club's lack of spending, he added: 'We played against a good team.
"In football you need time to work and players on the pitch to work and we didn't have until now".
"So I will have to focus on the players I have and in relation to these first couple of matches - maybe three matches because after Spurs (and Burnley on August 27 and September 1 respectively) there is (a) national team (break) and a couple of weeks to recover people and prepare people better".
