However, before they can even think about that, the Red Devils must prepare themselves for a trip to Anfield on Sunday, where they will meet Jürgen Klopp's unbeaten Liverpool side, and they may have to do so without Rashford.
"You've got to take [chances] once in a while", Solskjaer said. "He couldn't run. He's struggled a little bit with a couple of knocks in his back recently and now he's got another one".
The Times chief football writer Henry Winter says clubs need to be careful "not to flog" the players too much by playing them in too many games.
Manchester United also face the prospect of working without their top scorer Rashford for the crunch match as the England forward hobbled off the pitch during the FA cup third round replay against Wolves on Wednesday.
This has been Mata's best month of the season, which is not hard to conclude, since all two of his goals and four assists have come in the best 30-odd days, since that game against AZ Alkmaar in Europa League.
But United, who failed to muster a shot on target in the 0-0 draw at Molineux 10 days ago for the first time since January 2015, largely bossed the second half and probably deserved to shade the contest.
In the aftermath of that game, which Wolves lost 1-0, manager Nuno Espirito Santo hit out at the decisions being made at Stockley Park, saying: "I don't like it that we are seeing decisions being taken by referees miles and miles away". A 3rd round replay was certainly an unwelcome feature in his side's hectic schedule and Ole Gunnar Solskjaer can thank Juan Mata's deft finish for the victor.
"I've been told by someone who would know, who I trust 100 percent and who has given me stuff in the past and been bang on so is clearly informed", he insisted. They play in a certain way and they do it very well. Now we have got a different one.
"We've got five or six games now until then, we've just got to stick at it, hang in there until then, get the performances and the results that we hope we're going to get, and then use that to get some vitamin D".
