Arsenal boss Arsene Wenger is delighted with the form of goalkeeper Wojciech Szczesny.
The 21-year-old was at his brilliant best at Liverpool on Saturday.
"I always give him my honest opinion of his performance," Wenger told arsenal.com.
"He takes it very well because I have always been honest with him, even as a young goalkeeper at 16 or 17. That will always remain.
"He was outstanding at Liverpool and I am the first to say that when he deserves it. For me, he is an outstanding talent with an outstanding future. But talent without effort is nothing. he knows that and I have to make sure he knows that."
