Chelsea ace Willian says he is determined to earn a starting spot at Stamford Bridge this season.
The Brazilian joined Chelsea over the summer with the aim of earning spot for his national side at the World Cup on home soil next year.
In the face of fierce competition the former Anzhi Makhachkala ace has struggled for regular game time in west London so far, and has largely had to make do with appearances in cup competitions.
However he looks to have taken his first step towards his goal after being named in Brazil's squad for their upcoming friendlies against Honduras and Chile.
On the opportunities handed to him by Jose Mourinho, the 25-year-old has impressed, most notably with a fine goal against Norwich earlier in the season and by helping the Blues reach the quarter-finals of the Capital One cup at Arsenal's expense this week.
Now the Chelsea forward says he hopes to use his performance against Arsenal as a springboard to more regular Premier League action.
"I am happy with myself, as I think I am improving every match," he told Lancenet. "I ran a lot, I managed to create some good plays and help the team.
"I'm feeling physically better and slowly becoming more confident.
"I am sure I'll grow even more, improve with every game. What is important is that I am happy and that I am earning my place."
Chelsea made it through to the last eight of the Capital One cup in convincing fashion, with goals from Cesar Azpilicueta and Juan Mata sealing the win at the Emirates Stadium.
"Playing a derby [against Arsenal] as important as that one was a different feeling," he continued.
"I am very happy to have achieved that beautiful win and to have advanced to the next round.
"Arsenal's team have a lot of quality, which is why they top the league, beating them at this moment makes our victory even more commendable."
Willian's next opportunity to impress comes on Saturdya, when Chelsea travel to take on Newcastle.
