Kieffer Moore was City's first summer signing in 2020.
The Welsh international forward signed a three-year deal at Cardiff City Stadium, joining from Wigan Athletic for an undisclosed fee.
Kieffer spent one season in Greater Manchester after impressing during an 18 month spell with Barnsley. He made 36 league appearances and scored ten times in the Championship for Wigan in 2019/20.
Torquay-born, Moore is eligible to play for Wales through his maternal grandfather and made his debut for Ryan Giggs in September 2019. He has three international goals to date, netting against Slovakia and Azerbaijan in the successful UEFA Euro 2020 qualification campaign and Finland during the UEFA Nations League, in early September 2020.
