Could've said he was happy to be back and wants to concentrate on the future. Could've said nothing at all.
To be fair, the article comes from an interview he did with El Tiempo,
here as linked in the original CN article.
The quoted response is to a very clear and direct question,

¿Por qué el dopaje?.
It's clear that Valverde is going to have to answer questions about the suspension, and in some cases he's not going to be able to fob interviewers off with the much more palatable style of response that you outline.
