Crystal Palace are reportedly set to snap up Arsenal academy prospect Dan Casey, after reaching an agreement with the Gunners over a compensation package.The 18-year-old attacking midfielder turned down a professional contract from Arsenal earlier this summer, opting instead to pursue a fresh challenge elsewhere. Palace have now stepped in, and according to The Standard, the deal is on the verge of being finalised.Casey caught plenty of attention during the 2023/24 campaign, where he excelled at youth level by netting 18 goals in 21 appearances for Arsenal’s under-18s. His performances have marked him out as one of the brightest young talents in English football.A boyhood Liverpool supporterDespite his Arsenal ties, Casey has admitted in the past that he grew up a Liverpool fan, idolising Steven Gerrard and Philippe Coutinho. More recently, he’s spoken of his admiration for current Arsenal captain Martin Ødegaard, describing him as “a top player” and a major influence on his development.Why Palace makes senseThe Eagles have built a strong reputation for developing young players into first-team regulars, and Casey could follow a similar path if he adapts quickly. A move to Selhurst Park may also provide him with greater opportunities than staying at Arsenal, where competition for attacking roles is fierce.For Arsenal, losing such a promising talent is undoubtedly a blow. However, they’ve safeguarded their interests with a sell-on clause, ensuring they could still profit if Casey makes a big move later in his career.Should the teenager fulfil his potential, this transfer might prove to be a clever piece of business for Crystal Palace—and perhaps a regret for Arsenal.
