Arsenal playmaker Santi Cazorla is not surprised by those doubting the club's ability to win the Premier League title after nine years without a major trophy.
The Gunners returned to the top with a 2-1 victory at Aston Villa, one point clear of Manchester City while Chelsea are just two points behind Arsene Wenger's team.
However, there are still some concerns over Arsenal's ability to hold onto their lead until the end of the season.
When asked by Spanish radio station Cadena Ser, Cazorla said: "It is normal that people think like that after nine years without winning any trophy.
"People have doubts about us keeping the lead but we believe that we can do it. We have shown that if we keep playing well we can fight for the Premier League. Now we have to win Fulham in our next game
The team are in the good path. We have to continue the winning streak as our rivals are also very strong."
The Spanish playmaker, who is in his second season at the Emirates Stadium, also praised his manager and spoke about the tough competition for places in Arsenal's midfield.
"Wenger always trust in me. I am playing a lot despite I have pain in my ankle since the start of the season. I feel better every day and Wenger has always shown his confidence in me giving me the freedom that I need in the pitch.
"With players like (Mesut) Ozil, (Theo) Walcott, (Aaron) Ramsey or (Thomas Rosicky) is very difficul to play as a starter but the boss is giving me many chances to play."
