Roberto Soldado says he has not been good enough in the early days of his Tottenham career but has backed himself to succeed soon.
The Spanish international striker joined from Valencia in the summer for £26m - a club record fee at the time.
After scoring 24 goals in La Liga last term, the 28-year-old was expected to eradicate the striker issues that plagued Tottenham through the 2012/13 season.
However, although managing four goals in the Premier League thus far, three have been from the penalty spot, inciting criticism that he fails to contribute to open play.
Soldado says his slow start to life in north London can be put down to his struggle to adapt to the way Andre Villas-Boas sets up the Tottenham team, but believes he is close to cracking the code.
"I have scored six goals but I would like to score many more," Soldado told reporters.
"I am a realist and I know that on the pitch I am not happy with everything.
"I am not combining with my team-mates how I would like but I know I am very close. I'm striving to get to top form and play at 100 per cent. I am convinced that I am almost there.
"I don't want to stop scoring goals, that's why Tottenham signed me. I'm not 100 per cent but the manager has put his faith in me end he is giving me minutes. Scoring more goals for this team is my target.
"I have scored decisive goals that have won matches, they might have been penalties, but I want more and the manager wants more and that is what I want to give to the fans."
Soldado says the changes to his environment have slowed his adaption to life in England and has cited the weather as a main concern.
But the former Real Madrid striker says he is only looking at the positives.
"The first thing that people tell you when you make a change like this is about the weather," Soldado told Spurs TV.
"Valencia has 10 or 11 months of sun and here's the opposite - there's only two or three months, but you have to look at the positives as well from this. I only look at the positives."
