Southampton boss Ralph Hasenhuttl has not been surprised by Erling Haaland's stunning scoring form since his arrival at Manchester City.
Haaland took his season's tally to 19 in just 12 appearances in all competitions with a double in City's 5-0 midweek Champions League win against Copenhagen.
Hasenhuttl's side will attempt to stop the red-hot Norway striker on Saturday when they take on City at the Etihad Stadium.
'It's not that surprising that a good player coming into a good team can be a successful goal scorer,' Hasenhuttl said.
