Kieran Sadlier arrived at AESSEAL in August 2020 to become Paul Warne’s second summer signing ahead of the 2020/21 Sky Bet Championship campaign, the exciting attacker signed a two-year-deal to keep him with the Millers until 2022.

Sadlier enjoyed a successful spell with South Yorkshire neighbours Doncaster Rovers, where he was a standout performer, finding the net 11 times to finish as the club’s top scorer.

The 25-year-old came through the ranks at Cambridge United before making a move to West Ham United in 2005, signing his first pro-deal with the Hammers in 2013. Following two years in East London he went on to enjoy spells at Scottish outfit St Mirren, Halifax Town (loan) and Peterborough United before making his way to Ireland.

He was prolific in the League of Ireland Premier Division with Cork City and Sligo Rovers, earning him a move back to England with Doncaster Rovers. Sadlier replicated this fine goal-scoring form with Rovers during the 2019/20 campaign, prompting Millers boss Paul Warne to snap him up, following the expiration of his contract.

After a promising start to life in Rotherham colours - which saw him net his first goal for the club against Birmingham City in September - Sadlier was faced with a lengthy injury lay-off after sustaining an injury in November, eventually ending the campaign with 16 appearances in all competitions.
