He has been with Chelsea for about a year, after moving from Aston Villa. However, last season was affected by hamstring injuries, which limited his playing time.
Kellyman, who is 19 years old, has mostly played for Chelsea's under-21 team, making just four appearances. He has yet to make his senior debut for the club.
According to reports, Kellyman is optimistic about joining Cardiff City. He believes that playing in League One will give him the opportunity to consistently play football, which is essential for his development as a player.
