Sebastian Polter has scored in his last two appearances for Queens Park Rangers.
Polter was brought to QPR from Mainz in the summer transfer window, but he has found appearances hard to come by at Loftus Road.
The target man played just seven times prior to Hasselbaink’s arrival, but he has been awarded a run of games since the Dutchman was appointed.
Polter has now featured in QPR’s last five matches, and he has hit the back of the net in his last two outings.
And, although he Polter still not won over all the supporters at Loftus Road, Hasselbaink says that the 24-year-old will get better with experience.
“Everyone talks about Charlie [Austin] not being available, but he is injured and that is that,” Hasselbaink said.
“Sebastian is by no means the finished article – yes, there are a lot of improvements he can make –but he gives us an outlet, works hard for the team and has now scored two goals in as many games.
“With hard work on the training ground, which he shows, he will get better and better for us.”
QPR supporters’ frustrations with Polter could audibly be heard during their recent 2-1 defeat to Hull City, but if he keeps hitting the back of the net, Hasselbaink will feel justified in selecting the powerful front man.
Hassebaink will hope that the striker’s goalscoring form continues, as he is still searching for his first win since taking over at the R’s.
The former Burton Albion boss has now been in charge for six matches, but he has only been able to guide Rangers to four draws and two defeats.
