Age is catching up with him, finally, you have to accept it. We, most likely, won't see Alejandro Valverde's season-long immortal form anymore. But what we could see is one long peak like last year, hopefully in the summer/late summer. He's still capable to win big races, but the difference is that now he needs to build form much longer, and now he needs to be more careful where, when and how he races throughout the year, cause those old days when he had the form whenever he sits on the bike are most likely gone.
