Arsenal boss Arsene Wenger was delighted with the performance of Aaron Ramsey in victory at Chelsea.
Wenger feels Ramsey is improving week-by-week.
"What people forget about players like Wojciech, Ramsey and Wilshere are all 19-20 years old," said Wenger.
"They are top quality and it is normal that they improve from game to game and from year to year."
