Alexander Isak agent aims one final dig at Newcastle United as war of words continues at executive level

Swedish football player Alexander Isak (C) arrives to attend a training session with Sweden's national team in Bosön in Lidingö on the outskirts of Stockholm, Sweden, on September 2, 2025. Record spending of £3 billion ($4 billion) during the summer transfer window further cements the Premier League as the "most competitive in world football", according to financial experts Deloitte. The window closed in dramatic style late on Monday, September 1, 2025, when Liverpool announced the British record £125 million signing of Newcastle striker Alexander Isak after a day of big moves.

Newcastle United's board of directors could be the target of a post-transfer window war of words from Alexander Isak's agent Vlado Lemic.

The Croatian-born intermediary has brokered several high-profile transfers throughout his career as a football agent, although few will be as lucrative as the £130 million transfer which has seen Isak join Liverpool for a British record fee.

The 59-year-old supposedly played a leading role in Arjen Robben and Mateja Kezman's 2004 moves to Chelsea, having developed a relationship with selling club PSV Eindhoven and then-Chelsea owner, the Russian oligarch Roman Abramovich.

Royston Drenthe's 2007 switch from Feyenoord to Real Madrid, Branislav Ivanovic's transfer to Chelsea, Samuel Eto'o's move to Anzhi Makhachkala and Luka Modric's Tottenham Hotspur departure for The Galacticos in 2012 have all been credited to Isak's representative.

Lemic was approached for comment by talkSPORT host and journalist Jim White, the morning after Isak's Liverpool arrival was announced late into the evening on transfer deadline day.

In response to White, Lemic reportedly said: "It's nice when you have someone to be with, but it's even nicer when you know who you'll never be with again."

The agent's comments could be seen to refer to the Newcastle hierarchy, whom Lemic and Isak clashed with over the summer prior to resolving the dispute with a transfer late in the window.

White's radio co-host, former Crystal Palace chairman Simon Jordan quipped: "I'm sure he'll be welcome in Newcastle."

Many Newcastle supporters deem Isak's behaviour throughout the summer to have indefinitely tarnished his St. James' Park legacy.

The striker played a key role in the club's Carabao Cup triumph last season, scoring what proved to be the winning goal that ended the club's 70-year domestic trophy drought. Newcastle released a 37-word statement confirming the player's exit on Monday night.

In his first interview as a Liverpool player, Isak described the summer as a 'long' and 'tricky' affair. He has taken the No.9 shirt at Anfield and could make his debut following the international break.
