I have no idea what you people are talking about, this guy is horrible. And seeing as how this is not a video game, regardless of his age, he's not magically gonna improve significantly in any department, especially in terms of speed. Best case scenario, he gets 5-10% better over time, which would still be pretty bad. I would've preferred if we kept Perez as a sub, he's way more explosive. This guy is just a snail, and I don't see him being of any relevance on the field be it as a starter, or as a sub. As a sub he's probably even worse, 'cause he comes in against relatively tired defenders and even then can't make a play if his life depended on it.
