There may not be life on Mackemland, but he insists there is life AFTER the experience.
McCarthy, who will be unveiled as the new manager of Wolves on his return from holiday, was sacked by the Black Cats in March as a woeful campaign for the Wearside club neared its end.
Sunderland won just three league games and broke their own record for the lowest points total in the Premiership as they returned to the Championship.
McCarthy: 'We won the Championship with players from the lower leagues and reserve teams who came in and did wonderfully well for us. Maybe it was just a step up too quick and maybe there were mistakes made by all parties.
'But no, I don't think for one minute it made me a bad manager, the experience has probably made me a better one.'
