Andre Schurrle has revealed that he left Chelsea for Wolfsburg because he felt that Blues boss Jose Mourinho did not trust him.
The Germany international spent 18 months at Stamford Bridge before signing for the Bundesliga outfit in February.
Schurrle, who had joined Chelsea from Bayer Leverkusen in June 2013, has said that he is unsure why Mourinho failed to have faith in him.
"I had a good time at Chelsea and was accepted in the team, so it's difficult to explain why I left," the forward told The Times.
"My performances were good as well, but there was a time in my second season when I felt I didn't have the manager's trust any more and I didn't play many matches from the start.
"I don't know why Mourinho didn't trust me. It all felt a bit weird to me. I started a few games, was on the bench for a few, then started some more."
Schurrle scored 14 goals in 64 appearances for Chelsea.
