Cavan Sullivan has already cemented his place in the senior team at Philadelphia Union this season, with six goals and five assists in 23 league appearances. His form has earned him a place in Mauricio Pochettino's most-recent USMNT squad. Sullivan has agreed to join Manchester City in 2028, but Real Madrid and Barcelona are keeping a close eye on his development. They could make a future move for the USMNT teenager if he doesn't make the breakthrough into their first XI quickly. Meanwhile, Arsenal are interested in a move for AFC Bournemouth forward Junior Kroupi in January once he has recovered from injury.
