Wolves beat Tottenham on Saturday, but McCarthy rested players for their next game at the weekend which is against Burnley
The Wolves boss has come under fire from the media and fans alike – but McCarthy insists he has no regrets.
He said: ”I only decided to change the team after Saturday’s result. All the player effort-ratings that our fitness coach works out were 9.5s or 10. We need to play at that level to get results against top teams and we can’t do it on a Saturday and then also on a Tuesday.
“I played the best team available to me tonight, the fittest, best and strongest team I could pick, that hadn’t played on Saturday.
“That was my best team available because they were all fresh legs. I can understand the fans but that is my first team.”
