Astana's Bosnia-Herzegovina international midfielder Ivan Bašić is reportedly a transfer target for Martin O'Neill at Celtic, who are monitoring his country's players at the World Cup. The 24-year-old is being watched closely by the club. The potential move could be part of a transfer for two players, as Celtic have also been linked with his international midfield partner, Benjamin Tahirovic. Bašić, who plays a more reserved role, is considered likely to be the less expensive of the two players. The midfielder, who has 18 caps for his country, joined Astana in July 2025 and his contract runs until December 2026. According to Transfermarkt, he has a current market value of €1.50m. In May 2026, reports claimed Levski Sofia submitted a €2.5 million offer, which Astana reportedly considered too low.
