Nikolas Polster, a 23-year-old Austrian goalkeeper for Wolfsberger, is being monitored by several Premier League clubs, including Wolves, Brentford, and Brighton. St Etienne is also reported to have an interest, and Celtic are also looking at the player. Polster's current club is in danger of relegation from the Austrian top-flight, which could lead to his departure. It is understood that both Wolves and Celtic believe the goalkeeper would fit within their playing budgets. Polster joined Wolfsberger in July 2024 and has a contract with the club until June 2027. He has yet to be capped for the Austrian national team. According to Transfermarkt, he has a current market value of €2.00m.
