Your assessment is a bit harsh. After that first match vs Uruguay, Costa Rica relied a bit too heavily on him, which didn't suit him as ball retention is far from his greatest asset. I think he will provide a spark off the bench and prove to be quite useful in terms of depth in the FW department.
And by the way, he played at Lorient (Ligue 1) 3 seasons ago, Real Betis (Liga BBVA) 2 seasons ago, and Olympiakos (Greek Superleague) this past season.
