Arsenal manager Arsene Wenger has reserved special praise for on-form striker Olivier Giroud.
The French forward worked tirelessly for his side as Arsenal overcame a resilient Crystal Palace on Saturday.
The striker's efforts were rewarded when in the 87th minute he turned Aaron Ramsey's delightful chipped pass into the net.
The away side were reduced to 10 men in the 65th minute and Giroud sacrificed much of his attacking threat by working hard when his team were out of possession.
And his work rate obviously impressed Wenger who was delighted with the former Montpellier man:
"That is what makes him great," said Wenger on Arsenal.com. "He missed some chances but always got the support of our fans because he shows he is ready for a fight. The fact that he kept going got him a goal."
the 27-year-old has started the season in fine form and after netting in Arsenal's midweek fixture with Dortmund his header sealed the three points against manager-less Palace.
The Gunners boss is impressed with his forward and has backed him to improve further.
"How much has he improved? I don't know. But he has. That's obvious to everybody, " said Wenger. "If he keeps working like that then he will improve again. I like his spirit."
Arsenal took the lead when Mikel Arteta converted a second-half penalty.
However, the same man was again in the action as he was controversially sent off for a challenge on former Gunner Marouane Chamakh.
Wenger was pleased with the fighting spirit the side showed after the Spaniard's dismissal.
"It was important not to make a mistake defensively and be patient because we always felt a goal would come," Wenger added.
"It's good to see that everybody puts a shift in when it's needed."
Next up for Arsenal is a Capital One Cup clash with Chelsea in what signals the start of a tricky period of games for the league leaders.
