Although McCarthy admitted that Wolves, who have leaked seven goals in their last two Premier League games, have had "a few knockbacks" during this transfer window, one player who has moved to Molineux is Dundee striker Leigh Griffiths.
McCarthy said that 20-year-old Griffiths is talented, but not ready for the first team just yet.
"He's scored 45 goals in 90 games and he's got an eye for goal," McCarthy added.
"He's not up to speed here yet, in terms of being a Premiership player, but he's hungry to do it and he wants to get there.
"He's not a player to come into our team now and suddenly start scoring.
"If we can work with him and improve him, we may well have got ourselves a little gem."
