Speaking to CNN about Manchester United’s form this season, Mourinho insisted that the Red Devils have made improvements.
“I think really at this moment in the Premier League we have one team, one club clearly better prepared than us in the past few years to be first and we have 18 clubs behind us. One in front of us, 18 behind us,” Mourinho told CNN.
“In the future we want to have 19 clubs behind us but this is the reality. And the reality is for people with a brain, with sense, with common sense, with knowledge of what sports is, we are in a moment of transition.
“Being in a moment of transition and still manage to do what he did last season and win trophies and to do what we are trying to do this season, which is still trying to win a trophy, and try to be second. I think we are in a good position.”
Manchester United will take on fourth-placed Tottenham Hotspur in the FA Cup semi-final at Wembley next month.
