Rotherham United's hunt for a new manager has suffered a setback as Mat Sadler has rejected the club's offer. Sadler, the former Walsall boss, had been in talks with the League Two club about taking charge at the New York Stadium. However, after lengthy discussions, Sadler has opted to reject the opportunity with the Millers. Lee Clark, the previous manager, left Rotherham earlier this summer despite being appointed in March as he failed to agree terms over a contract extension. Clark has since landed the Hartlepool job. Sadler had emerged as the leading candidate to land the job at the New York Stadium, but after failing to reach an agreement in talks, both parties have walked away. The Yorkshire club were in the Championship just two seasons ago, and their dramatic drop has raised concerns about their direction. Rotherham are undergoing major changes following their relegation to League Two, with the club looking to employ a new strategy to turn around their recent collapse. Steve McClaren, the former England manager, has been appointed as the club's director of football, and he will work alongside Rob Scott, the head of recruitment, to head up their transfer plans. The move for McClaren appears set to mark the start of the overhaul at the club, with the arrival of a new manager their biggest priority as things stand. Rotherham's relegation to League Two has been a significant blow to the club, and they will be looking to bounce back into League One as soon as possible. The club's fans will be hoping that the new manager can bring some stability and success to the team. With the new season approaching, Rotherham United will be looking to make a strong start and push for promotion.
