Bayern Munich are reportedly among a number of clubs showing interest in Brighton's 19-year-old defender, Luka Vuskovic. The Croatia international is also said to be monitored by Chelsea and Barcelona.
Elsewhere in the transfer market, AC Milan are reportedly keen on Bournemouth midfielder Alex Scott, 23. The England international's increasing value has not deterred the Italian club.
Liverpool are also reportedly interested in Barcelona defender Jules Kounde. The La Liga side is said to be open to offers of £60m for the France full-back. Additionally, Porto have increased the release clause for 20-year-old Brazil forward William Gomes to 100m euros (£85m) amid interest from Liverpool.
Chelsea reportedly remain interested in Monaco midfielder Lamine Camara, 22, after missing out on him in the summer. However, the Blues are not expected to meet the Ligue 1 club's 70m euro (£59m) valuation.
In youth prospects, Bayern Munich have held fresh talks with 16-year-old Manchester United attacking midfielder JJ Gabriel, though no offer has been made. Gabriel is reportedly leaning towards a move to Spain, with Barcelona and Real Madrid considered favourites to sign him. Manchester City also reportedly approached Borussia Dortmund in the summer to sign 17-year-old USA forward Mathis Albert.
