"I think I started to find my best form last season when I moved to Everton, that is for sure," he told evertonTV. "The last four months of last season I felt much more confident. They were much better than the first six months because I started playing and scoring goals and that gave me confidence.
"In my opinion it was the manager and my team-mates who helped me find that confidence. They pass that tranquility and that confidence to you and that's why I was able to find my best (form)."
Knowing throughout that officials were in talks to secure his return, he was overjoyed to find himself reporting to Finch Farm when pre-season training began.
"I was on holiday so my head was on holiday and I was looking forward to enjoying my holiday," he explained. "But my head was also remaining at Everton.
"Before the season finished, I realised that people were happy with me and there was a good opportunity for me to remain at the Club. I was happy with that and it was an easy decision to make because I get on very well with all the players here. To me it was a very easy decision to make.
"I haven't been able to sit down and have a private chat with the manager yet but during the first few days of training he told me he was very pleased for me to be at the Club and I told him the same thing."
