I feel like people watching this game will not believe how hard we trained this week.
Jose further spoke about the formidable mentality his team displayed at the Vitality stadium on Saturday, by adding: "When we are in control we have no problems, when the opponent is in control I think the team has problems".
"Manchester United changed things and made substitutions, but I was pleased with my players attitudes to the game and they gave everything to the match".
Juventus won 1-0 when they visited Old Trafford in a game in which United were punished for a slow start but improved after half-time - something that is becoming a theme of the season for Jose Mourinho's side.
He said on BT Sport: "They were much better than us in the first half, and we were better in the second. The first half, I think we learned from that and we showed that in the second half and on Wednesday you will see a difference".
Rashford and Alexis Sánchez, against Newcastle United, have both scored stoppage-time winners in recent weeks, which has also led to comparisons with Ferguson's reign, during which his team often prospered late on.
Roma had the best of the first half with a Federico Fazio header going dangerously close and Edin Dzeko firing wide after 20 minutes.
Ander Herrera was delighted with Manchester United's second-half performance in Saturday's 2-1 win at Bournemouth but conceded Jose Mourinho's men are making life hard for themselves. A lot of our aspects of our play were very good, especially in that opening period. "We are doing everything we can to get there, the 28-year-old said".
"We were ready for everything, I can't understand the mentality that brings me more white hair!"
Roma seemed to be heading for defeat when, five minutes from fulltime, Fiorentina goalkeeper Alban Lafont parried Aleksandar Kolarov's cross straight at Florenzi, who leveled with a scuffed volley.
"The team looked like we don't work tactically during the week which is obviously the worst feeling for me because we work so much and I expect my team to be really good and I feel really frustrated with that", Mourinho said.
"We are talking about one of the top two or three clubs in world football here, but they are not playing like that and I fear for them when they take on Juventus and City in the next week".
