Vicente Calderón Stadium
On 25 May 2010, Atlético Madrid officially announced that Mérida was on his way to the Vicente Calderón Stadium on a free transfer, after refusing Arsenal's contract offer at the end of the campaign. He scored his first official goal for his new club on 27 October in a 5–0 win against Universidad de Las Palmas CF for the Copa del Rey, repeating the feat in the second leg (1–1 draw at the Vicente Calderón Stadium).
