Gareth Barry believes Aston Villa team-mate Curtis Davies will prove himself at the club, despite being below par in his debut midweek.
Davies signed for Villa in the summer from West Brom and had missed the start of the season due to injury.
But the 22-year-old finally represented the Villans in their Carling Cup defeat by Leicester on Wednesday and after the game openly admitted he was poor.
However his skipper, Barry, is standing by the £8million defender, and feels he will prove himself in time.
"Curtis has given himself a bit of stick but he'll learn from that game," said Barry.
"It wasn't the great start he wanted to his Villa career - but I know Curtis will show everyone what a good player he is.
"He has high expectations for himself and that's something we should all have. The manager has brought him in because he adds quality to the squad and that hasn't changed after one match."
Meanwhile Davies' manager Martin O'Neill is hoping that the Leicester result will not be repeated again but remains down by the defeat.
He said: "I'm sure the players felt it as badly as I do. I'm a spokesman for myself and I'm sure Gareth Barry felt it badly because he wants to win something for the football club.
"We are out of the Carling Cup and Wednesday night was just really disappointing, I can't express it any other way.
"Hopefully it was a big one-off."
