With the oldest cup competition joining the Carling Cup and Champions League as trophies that will not be ending up at Old Trafford this season thanks to the 2-1 defeat at Liverpool, Park grasped for what remains.
"I am glad there is another match on Tuesday," said the South Korean.
"We can forget about this result quickly and look to the future.
"Then we have the Premier League and Europa League. We shouldn't mess up these two titles."
In fairness to Park, he is not the man to offer a forensic analysis of the latest failure.
However, it only takes a quick look at a fixture list that follows a midweek encounter against Stoke with a trip to Chelsea and them an Old Trafford meeting with Liverpool on February 11 to understand that unless United recover quickly, by the time they head to Amsterdam for the first leg of that Europa League last-32 tie with Ajax, it might be all they have left to play for.
And to achieve that, if those who are paid to analyse are to be believed, David de Gea needs to be axed.
"You have to think back to when United had Schmeichel and Van der Sar," observed Gareth Southgate on ITV1.
"They were such an important part of teams that won the league.
"Joe Hart looks like he might do that for Manchester City this year. It could end up being the difference between the sides."
Typically, former Red Devils skipper Roy Keane pulled no punches either.
"Goalkeeper is the most important position at Manchester United," said the Irishman.
"De Gea looked a bit nervous. When you have a nervous goalkeeper it can go through the whole team."
As Keane has already infuriated Sir Alex Ferguson once this season with his TV criticisms, he is clearly not worried about causing further annoyance.
However, the comments have credence, despite Ferguson's claim that his defenders did De Gea no favours by crowding him and making it impossible to reach the corner that ended with Daniel Agger heading Liverpool in front.
On too many occasions, De Gea needed his team-mates to provide the protection his slender frame cannot do alone.
The pass out of his box in the second half that nearly let Stewart Downing in and the dropped cross for a corner were nothing to do with team-mates.
They brought panic though, which is why Anders Lindegaard is virtually certain to return on Tuesday against opponents who did not give De Gea the battering he probably expected at the Britannia Stadium earlier this season.
Rio Ferdinand should also be available to face Tony Pulis' men, which could be important.
For, as well as Jonny Evans and Chris Smalling have done this season, their inexperience did not help in attempting to defend against Andy Carroll's flick from Jose Reina's goal-kick, even if it was Patrice Evra who was out of position to allow Dirk Kuyt to seal the tie.
"We always try to win," said Park. "That is the Manchester United way.
"But we lost concentration and gave them a goal."
It was not a great day for Evra, who was jeered every time he touched the ball and suffered more than most from the restrained attitude players of both sides thankfully adopted given the venom in the stands.
After flashpoints in the city earlier, some of the chanting was particularly distasteful even if police are investigating one alleged incident, the pictures of which were flashed around the world on Twitter.
Not that the United contingent travelled home discussing anything other than the game, which, at least, is what Ferguson would have wanted.
"The atmosphere wasn't too bad," said Park.
"It was the same as normal. Anfield is quite a difficult place to come and play.
"I didn't think it was particularly different."
