Fulham defender Brede Hangeland has hailed the impact of new teammate Pavel Pogrebnyak since his arrival at the club.
The Russian hitman moved to Craven Cottage on transfer deadline day and has wasted little time in finding goalscoring form.
A hat-trick in the Cottagers' 5-0 win over Wolves on Sunday means that he has now netted five times in three games.
"If it keeps going like this who knows where it is going to end? I'm very happy for him," said Hangeland.
"The goals are one thing, but he works so hard and that is what you want to see, especially as a defender."
Pogrebnyak is currently on loan at Fulham from German side Stuttgart, but manager Martin Jol has hinted that he would be keen on keeping the striker past the end of the season.
