Sporting KC was interested in acquiring 16-year-old attacking midfielder Cavan Sullivan from Philadelphia Union on a short-term loan until the summer. The Union quickly rejected the approach, as the club believes in Sullivan's standing within the first team. The dual US-German national joined the club on 09/05/2024 and has a contract until the end of 2028. In the current Major League Soccer season, Sullivan has made 5 appearances and provided 1 assist. He has previously been linked with Manchester City. According to Transfermarkt, Sullivan has a current market value of €4.50m.
