Queens Park Rangers beat Brentford 3-0 at Loftus Road yesterday.
Polter joined QPR from Mainz last summer and his initial start at Loftus Road was not encouraging.
The German front-man found the net just once in his first 10 appearances for Rangers, and a series of poor performances saw him drop out of contention.
At that stage many QPR supporters were fearing that the move would not work out, but Polter has started to show his quality more recently.
The 24-year-old has been a regular starter since Hasselbaink took charge and he has repaid his manager’s faith.
Polter has netted five goals in 14 matches, and he scored in Rangers’ 3-0 win against Brentford this weekend.
The target man has held off the challenge of January signing Conor Washington to establish his place in the team, and QPR fans are starting to be won over.
Polter put in a great display against Brentford, and here is the best reaction for R’s supporters on social media site Twitter to that performance.
Polter is a great asset for this club. He's not great but his passion for the club is second to none, much prefer Polts to Washington! #QPR— Owen (@QPRFORLIFE) March 12, 2016
Sebastian Polter is QPR's next cult hero. Believe— Dunstan Bentley (@dbhoops) March 12, 2016
He doesn't win much in the air, his second touch is a tackle and I'm not sure he knows the offside rule, but I bloody love Seb Polter. #QPR— Jordan James Foster (@JordanJFoster) March 12, 2016
What JFH is doing is getting the best out of the likes of Mass, Polter and Chery. All vital assets to the team but not performing w/CR #QPR— thomas nichols (@TomNicholss) March 12, 2016
Well done Rangers. Great effort special mention to polter and Henry. Get slated most weeks in here. #Qpr— Ben Ingram (@BenIngram3) March 12, 2016
Polter - 0/10 for skill, 10/10 for entertainment. Hilarious player to watch. Can see him becoming a bit of a cult hero #QPR— Michael (@MichaelHi92) March 12, 2016
I had doubted Polter's ability, Hill's legs, Faurlin's durability.I'm none too proud to say I was wrong on all 3 counts. #QPR— Ak$h4Y (@TheAkshayVara) March 12, 2016
