Arsenal manager Arsene Wenger says striker Park Chu-Young has the ability to make it big with the Gunners.
After hitting his first Arsenal goal in the Carling Cup win over Bolton Wanderers, Park started in the UEFA Champions League against Marseille ahead of last weekend's hat-trick hero Robin Van Persie.
However, the South Korean failed to make an impression, but Wenger isn't worried by the performance, insisting the former Monaco forward will show himself to be a quality acquisition.
"I think he played a little bit inhibited [on Tuesday]," he said. "His real game was against Bolton and on the night against Marseille I think he was a bit fazed by the pressure.
"You will see the real Park very quickly. We are [relying on him in January] but I have plenty of confidence in him. He will show how good a player he is.
"He is quick, intelligent, mobile, a good finisher and many of these aspects didn't come out on the night. He will be a good player for Arsenal."
Another Arsenal new signing who is still getting used to life in England is Brazilian Andre Santos, who opened his Barclays Premier League goal account against Chelsea last weekend.
The goal set the platform for Wenger's side to crush their London rivals at Stamford Bridge, and the 28-year-old says he's thrilled with the way he's settling in.
"It was a very important goal, especially because that was my first London derby," Santos said.
"I was very happy, I'm adapting to the English game quickly and I will keep working hard so that our team can grow in the competition."
