"All you had several headlines about what I said about different questions. It is not to defend myself but you take the headline out of context."
"What we like to show Romelu is that we at Everton will grow, we will be bigger and we will fight for titles," he said.
"If you look now at Everton, if Everton stays at this level then of course it is not good that he finishes his career at Everton because he is one of the best strikers and he is still 23."
