Aston Villa have beaten Rangers and Tottenham Hotspur to the signature of Caleb Chukwuemeka.
The 19-year-old has joined Villa from League Two Northampton for an initial fee of around £300,000 with add-ons in the deal that could take the eventual figure up to seven figures.
Chukwuemeka is the brother of England under-18 starlet Carney, 17, who is considered one of Villa's brightest talents.
Academy manager Mark Harrison said: "We are delighted that Caleb has joined us. He has been a player we have been monitoring for a while now and has continued to develop well at Northampton, making a number of appearances last season.
"He is an exciting attacking player with an eye for goal and we feel has a lot of potential. We are really looking forward to working with him.
"I would like to thank Northampton for the way in which they've handled this transfer."
