Wolves manager Mick McCarthy hopes the signing of Luton Town right-back Kevin Foley will help to add competition for places at Molineux.
The 22-year-old has signed a three-year deal after completing his switch from Kenilworth Road for an undisclosed fee.
McCarthy told Wolves' official website: "Kevin was outstanding when he played against us at Wolves last season. We've had him watched quite a lot since then.
"We play 4-4-2 and he gives us another option.
"Mark Little has got an ankle injury that's causing us a bit of concern, and Foley gives us competition for places and, at his age, he's destined to get better."
