Wolves have announced the signing of Yerson Mosquera from Colombian side Atletico Nacional.
The Molineux outfit has paid a fee of around £4.5million for the 20-year-old centre-half.
Mosquera is the first signing of the Bruno Lage era at Wolves.
Wolves technical director Scott Sellars said: "We've been monitoring Yerson for quite a while, and there has been a lot of interest from clubs across Europe, including some of the biggest names in the Premier League.
"They all see his potential and quality, as do we, but we spoke to him about the pathway we have at the club, and he believes Wolves is the best fit for him.
"He's a centre-back who's very athletic, very aggressive, very competitive and has a great attitude to defending – he wants to defend, he wants to make tackles and headers, and has great presence in both boxes, but he's also very good technically and very composed on the ball.
"He's certainly a player with a high ceiling, someone who is highly regarded in Colombia and we believe the attributes he has will fit very well into the Premier League and into our squad.
"Our new head coach Bruno has been involved in the process, has looked at the player, and together we feel Yerson has the perfect profile to come in and improve the depth of the squad."
