Rio Ferdinand thinks Manchester City striker Erling Haaland has brought a 'fear' factor that has never been seen before in the Premier League.
Haaland scored his third hat-trick of the season in the Manchester derby on Sunday, and has now netted 14 goals in just eight league games since arriving at the Etihad Stadium in July.
The 22-year-old already looks to be running away with the Golden Boot, but Ferdinand has admitted that he has been taken aback by how opponents have tried to play against him, and has questioned why defenders have not tried to be more physical with the forward.
