“We earned our luck today by hard work, by good mentality,” Tuchel said. “It’s not the most easy time for us. We don’t play at the highest level.”
The visitors did at the start in Manchester when Kylian Mbappé’s deflected shot bounced into the path of Neymar to score from the near post.
It took David de Gea’s save, palming away Alessandro Florenzi’s shot, to prevent the deficit from growing bigger for United.
Good fortune came in the form of Fred not being sent off for pushing his head toward Leandro Paredes, despite a VAR review.
“To give a yellow card I was very surprised,” Tuchel said. “It says he touched him but not hard enough for a red card?”
After the reprieve, United drew level when Anthony Martial’s shot was parried by Kaylor Navas and Rashford’s strike deflected off Danilo past the goalkeeper for his sixth goal in five European games.
Fortunately again for United, Paredes was booked rather than Fred, who stepped on the PSG midfielder’s foot.
That still didn’t prompt Solskjær to substitute Fred at the break.
United had chances to go in front after the break when Martial lifted a shot over and Edinson Cavani tried to chip Navas.
“It could perhaps have been completely different if they had scored,” Herrera said. “But we have players who can kill a match.”
