Thorgan acknowledged that his brother has yet to impress at Los Blancos but expressed his hope that he can do so in his third campaign at the club.
"The Spanish press is not the easiest [to deal with], we have seen it with other players," he told the press conference on Tuesday.
"On the other hand, it is understandable that they are critical because Eden has not been able to show much in the last two years.
"I think the Spanish press knows it and knows the quality [Eden] has and I hope he can prove himself next season."
"The good thing about being in Eden's shadow is that there was not much talk about me when I was dealing with muscle injuries," he added.
"I did not know how to get back on the field, because it was the first time I had an injury.
"I had to learn when I was at 100 percent and I could return. It was a difficult season personally and medically.
"But collectively we had a great season with the cup win. That was my first team trophy. I played fewer games, but now I am fresh at the right time."
