The German was disappointed when his proposed move from Bayer Leverkusen to Stamford Bridge fell through last summer and is now determined to kick on
The 22-year-old finally agreed a €21 million switch from Bayer Leverkusen in June, a year after the Blues had first registered their interest in signing him.
Schurrle says he was aware of the north Londoners' desire to bring him to the Premier League and is delighted that the transfer eventually went through.
"I always hoped this move would happen," he told The Guardian. "It took a long time, and I'd wanted to come last year to Chelsea and it hadn't worked out.
"It wasn't my decision. It was the decision of Bayer Leverkusen, they didn't want me to go and I had to make the best of the situation.
"It was a missed opportunity, of course, but I said to myself I had to do my best in every match and every training session and it would come at another time. So it has proved. I had the contact all the time and now I'm very happy to be here."
The Germany international went on to score 11 goals as Leverkusen finished third and qualified for the Champions League.
However, Schurrle also admitted that it was difficult for him to concentrate after his proposed move to Chelsea fell through last summer.
"At the beginning it was really hard for me," the Germany international added. "I wanted this so much and it hadn't worked out. But I had to do my work for Bayer Leverkusen and improve myself, and that's what happened.
"I wanted to be professional in all ways. The beginning was hard but afterwards it was okay. We had a good team. Now I'm here, and for a lot of money.
"There's no extra pressure on me because of that, but it makes me proud that the club wanted me that much and paid the money. I will give them my best."
