McCarthy revealed last month that he had told Halford his days at Molineux could be numbered if he failed to make an impression in the build-up to the new campaign. But the £2m signing from Sunderland has succeeded in winning over the former Republic of Ireland boss. McCarthy said: "Let's give Greg a bit of credit. He's trained well in pre-season. "Why would I even question that someone of his ability shouldn't be at the club? "He's got lots to offer. Now he's done it for us and, fair play to him, he's had a good pre-season. "Since he came back at the start of the summer, he has shown a desire to stay and I can't ask for anymore than that." Meanwhile, McCarthy revealed he has received no approaches from clubs interested in taking young striker Sam Vokes out on loan. Wales international Vokes had a loan spell at Leeds last season and has been linked with a temporary move to Crystal Palace in the coming campaign. McCarthy said: "No one has spoken to me about it and, until anyone does, he won't be going anywhere."
