Wolves manager Mick McCarthy has admitted the settled nature of his first-choice team sometimes impacts on the rest of his squad.[LNB] McCarthy is likely to recall experienced players such as Karl Henry and Jody Craddock to his starting 11 for the match against Aston Villa on Sunday in the wake of the midweek Carling Cup win over Notts County.[LNB]He said: "That is probably a problem sometimes.[LNB]"Most of the lads know I haven't really got any selection dilemmas. I'm giving them a game.[LNB]"We haven't played badly, so making all of those changes and saying 'play well tonight, and you're going to be in the side', that's not the case and they'll know that."[LNB]However, McCarthy said that players who do impress come into contention later in the season.[LNB]"I made loads of changes at Man United (in the league last year) and eight of them ended up in the team at West Ham."[LNB]Despite McCarthy's pre-season spending, the Wolves manager feels that survival this year will be as tough as last season.[LNB]"I don't think it changes," he said. "People keep asking me about this second season syndrome and I say I don't know because I've never had one.[LNB]"We had a fantastic start up until two away games against the Europa League finalists and a Champions League team (Fulham and Tottenham), and we lost them both.[LNB]"Now we're playing Villa at home, Wigan away and West Ham at home, maybe games that could be seen as being as tough as two away ties in London."
