Alexis Sanchez has insisted that he can only get better after completing his first season at Barcelona.
The 23-year-old Chilean, who scored 11 goals in the last campaign, joined from Udinese in July 2011 for an initial fee of around £22m.
"We haven't seen the best of Alexis yet," Sanchez told reporters.
"I am finding some form and as each game goes by I am improving a little more."
Barca are currently top of the La Liga table thanks to five wins from their first five matches.
