Manchester United now hold the fifth spot in the Premier League table with 34 points.
Despite only being on the pitch for 15 minutes, Rashford was forced to come off in the tie, just days ahead of the match with Liverpool.
"I'm going to give them a few days off, so I don't know where they'll all scatter around but we'll stay in Europe", he said.
Ruddy - who replaced Rui Patricio in goal in Wolves' only change from the weekend draw against Newcastle - was able to get enough contact on the ball to prevent James dashing by him after Mata's expert clip over the top. "If we get something that we can tell you about, we will, but I've got no news now". That's the core of what the team is going to be moving forward, for me.More news: US, China set to sign vital trade truce
The brief cameo from United's top goalscorer coincided with the only goal as Mata ensured Ole Gunnar Solskjaer's men will travel to either Watford or Tranmere on January 26th. "This is the point at which we should feel, and many of today's fans have experienced a time when we have consistently won the league".
"Let the boy settle in now before we talk about England and the Euros", Solskjaer said.
"It's been five games we haven't beaten Wolves".
"We finally beat them".
But Solskjaer explained that the note was mostly to do with his side veering out of shape throughout the clash.More news: Big Ben won't bong for Brexit
"We looked at the Middle East, but that will definitely not happen".
"Dan [James] had three or four great opportunities one-on-one with the keeper".
While Manchester United has not banned players from heading to Dubai, they have decided not to take the entire team to the region, and Solskjaer acknowledges that the current situation transcends matters in the field.
With United well off the pace in the Premier League and needing to overturn a 3-1 first-leg deficit to rivals Manchester City in the semi-finals of the Carabao Cup, Solskjaer is looking to the FA Cup as the most realistic prospect of silverware this season.More news: Kashmir gets partial internet but no social media
