Marc-Andre ter Stegen has no doubts he is a better player for his time with Barcelona.
The former Borussia Monchengladbach goalkeeper is in his third year with Barca.
"In general, I am a more mature person now. A lot has happened over the last three years. I'm starting my fourth season here. I have had a wonderful time here and I am delighted to continue to impose myself here, because that is what I want to do," said the German.
"We all have the chance to continue to be successful. This is what Barcelona always wanted and I think we all have the same goal, we all want to continue winning matches."
