He has 10 goals in his first nine appearances overall for Monaco to go along with two assists, making Biereth the top scorer in Europe’s top five leagues so far in 2025 as he became the first player to score three hat-tricks in his first seven Ligue 1 games for 70 years, per Stats Foot and Get French Football News.
The £4m deal to sell Biereth to Sturm Graz was a good one for Arsenal at the time as they included a sell-on fee that later banked them another seven-figure sum believed to be £2m, but they can also now be forgiven for wondering what might have been had they held on to him amidst an ongoing attacking injury crisis that has seen strikers Kai Havertz and Gabriel Jesus ruled out for the rest of the season and the likes of Bukayo Saka and Gabriel Martinelli unlikely to be back before the March international break.
He then dispatched a tap-in after the break to set the seal on another memorable treble, his third in his first nine games for his new club and his first seven appearances in Ligue 1 having done likewise in the 4-2 win over Auxerre on February 1 and in the 7-1 demolition of Nantes two weeks later.
He also had six in 15 for Motherwell and two in 13 for RKC Waalwijk, but never managed a senior appearance for Arsenal despite having also been prolific for Fulham at youth level before joining their London rivals in 2021 and going on to be an unused substitute for the first team on a handful of occasions in the 2021/22 season amid an impressive run with the Under-23s.
Biereth and fellow Danish youth international Chido Obi might both be featuring for Arsenal’s first team now had they stayed put, the latter having rejected the chance to stay with the Gunners last year after an astonishing scoring run for the academy as he joined rivals Manchester United instead.
