Arsenal midfielder Denilson believes a positive mental attitude has helped him to improve this season.
The Brazilian has emerged as a key player in recent months with Arsene Wenger's options often limited due to injuries.
Having joined the Gunners in 2006, the 21-year-old is delighted to be playing more regularly but believes he can develop his game further.
He said: "I feel I have improved a lot and every day there is room to improve more.
"Nobody is perfect and I wish I could perform brilliantly every match, but I always do my best to stay on in the team.
"I have been given the opportunity and I believe I am making the most of it.
"I know about my potential and I am still working to stay as long as possible in the first team.
"When you arrive at the training ground you have to forget everything outside and focus on your job - you have to think not only about yourself, but also of the team and the manager who is the one giving you that trust."
Denilson feels Arsenal have learned the lessons of earlier in the season and should now enjoy a strong finish to the campaign.
Speaking before Saturday's goalless draw with Sunderland, he told Arsenal TV Online: "I believe we are way more resilient.
"Since January we have been quite balanced and we have been winning the games we need."
