Does changing coach mean a change in fortunes?

Real Madrid, Manchester United and Celtic have all parted company with their head coach in 2025 while New Zealand's dismissal of Scott Robertson sent shockwaves around international rugby union. Elsewhere, Buffalo Bills' Sean McDermott became the eighth NFL head coach to leave their position in the month of January and the 10th since the start of the season. That was after Buffalo became the first NFL team to win a play-off round in six consecutive seasons but not reach the Super Bowl.

NFL and American sports expert, Mike Carlson, explains to Ed Harry why McDermott's dismissal makes the least sense of the January firings but is part of a wider trend in the sport. The BBC's rugby union correspondent, Chris Jones, says international rugby is unlikely to follow suit despite the All Blacks' unprecedented sacking of Robertson by the three time World Champions.
