Kosta Nedeljkovic makes ‘wasn’t the best’ admission after sealing Aston Villa transferKosta Nedeljkovic joins RB Leipzig on loan until the end of the season, with an option to buy for over £12m. The 19-year-old defender made only 10 appearances for Aston Villa in the first half of the season. Nedeljkovic is eager to get playing regularly in the Bundesliga and hopes to prove his worth. RB Leipzig sees potential in Nedeljkovic and aims to provide him with opportunities to develop.
