The following campaign, Adán was selected for the first team's United States tour in August 2006. He served as backup to captainJordi Codina in Real Madrid Castilla, until the latter's promotion to the main squad.
Adán made his debut in 2006–07's Segunda División on 27 August 2006, in a 1–1 away draw with CD Castellón.[6] He appeared in six league matches as Real's reserves were eventually relegated.[7]
After the sale of Codina to neighbours Getafe CF, Adán was promoted to the senior squad for pre-season training in the 2009–10 campaign. While still featuring mostly for the B's, he was third choice in the first team behind Iker Casillas and Jerzy Dudek.[8]
On 8 December 2010, Adán played his first competitive game for Real Madrid, coming on as a substitute for the injured Dudek in the 44th minute of the 4–0 home win against AJ Auxerre in the group stage of the UEFA Champions League; the Merengues had already won their group, and manager José Mourinho rested several starters.[9] The following month, he featured the full 90 minutes in a 2–0 loss at Levante UD in the round of 16 of the Copa del Rey (8–2 on aggregate).[10]
Adán made his La Liga debut on 13 February 2011, replacing sent off Casillas in the second minute of a 1–0 away victory over RCD Espanyol.[11] Starting in the following matchday, at home against Levante, he kept a clean sheet in a 2–0 win.[12]
On 22 December 2012, Adán relegated longtime incumbent Casillas to the bench in a 3–2 away loss to Málaga CF; Mourinho defended his controversial decision in his post-match comments by saying: "It's a technical decision. The coach analyses the situation, looks at the players at his disposal and chooses his team. At the moment, for me and my coaching staff, Adán is better than Iker".[13] He retained his place for the next game, being sent off in the early minutes of an eventual 4–3 home defeat of Real Sociedad after giving away a penalty.[14]
