The 24-year-old Germany star was sold to the Bundesliga side in January for a fee in the region ??22m but made??14 Premier League appearances and scored three goals in the campaign prior to that.
Schurrle told BBC World Service’s World Football programme: “I didn’t know that I’d get a medal when I didn’t play most of the second half of the season.
“Jose Mourinho sent me a text to say that I’d get a medal and he asked me to??come to the last game (against Sunderland on May 24). That was very nice for??me.
“I’m really happy for the boys. They played a very good second half of the??season so of course for me it’s good to get a medal but the boys did the??work.
“I had the World Cup which was very perfect for me and the start of the season??was good as well,” he added.
“Then there came a little bit of a period for me where my body didn’t feel??very good, I was not clear in my head and I didn’t have as many good moments for??Chelsea.
“I wanted to come back to the Bundesliga, I wanted to feel a little bit more??in the team and to get a bit more playing time.
“I love Chelsea still, I’m not frustrated, it was a great experience.”
