He acknowledged the chatter around Luka’s arrival but noted the youngster will need time to adapt to the demands of playing for Brighton and the Premier League, he added.
Even so, the club is confident he’ll take it all in his stride.
Vuskovic will take the place of Netherlands centre-back Jan Paul van Hecke in Hurzeler’s squad; van Hecke has gone the other way, signing a long-term deal with Spurs worth £52m.
Born in Split, Vuskovic progressed through Hajduk’s academy, debuting in Croatia’s top flight at just 16—the club’s youngest-ever player—and later becoming their youngest goalscorer.
Following a standout campaign in the Bundesliga last season, he was named Rookie of the Season and included in the league’s Team of the Year.
He has six senior caps and one goal for Croatia, and made his World Cup debut against England in last month’s group stage.
Brighton open the new Premier League season at home to Aston Villa on Sunday, 23 August at 14:00 BST.
