Wednesday put in a remarkable performance at Hillsborough as they put five goals passed Cardiff to climb off the foot of the Championship table and secure their biggest win of the year, giving manager, Darren Moore something to smile about while watching at home.
Moore wasn’t alongside McCarthy on the touchline after testing positive for COVID-19, but his opposite number was certainly impressed with what the Wednesday boss has done since his arrival.
Speaking to the media after the game, the Cardiff boss said, "It was a humbling experience this evening, that's for sure… The first goal set them up with a bit more confidence than they would have done, with where they are.
"Having watched it back we should have defended it better, let’s put it that way, that's disappointing.
"The second goal, I'm not sure what we can do to stop that, to be quite honest with you. Maybe stop it at source from the throw-in? But they've worked it well. The cross from the wing back and the finish from (Paterson; well it was an amazing goal.
"The third one, I'm disappointed we gave away the free-kick away, but again, nothing Dillon (Phillips) can do about it.”
He went on to give credit to the opposition, saying it’s probably their best performance of the campaign, adding, "I thought we started the second half well, we've had a couple of scrambles and couldn't score and we've been punished for throwing men forward and they've caught us on the break twice.
"But they were considerably better. Being 3-0 up certainly helps, but it was the worst performance we have had since since I've been here. And I imagine it's the best Sheffield Wednesday performance all season."
Now the challenge for Wednesday is to build on this performance against Queens Park Rangers on Saturday as they look to try and chip away at their deficit even further in their push for Championship survival.
The Owls are currently 23rd and six points off safety.
