On 19 January 2011, Corona scored one of Almería's most important goals, in a 3–2 win at Deportivo de La Coruña (4–2 on aggregate), with the club reaching the semi-finals of the Copa del Rey for the first time ever. On 9 April, through a counter-attack, he opened the score for the last-placed team at FC Barcelona – his second goal of the season – but the hosts eventually won it 3–1, and the visitors eventually suffered relegation after a four-year stay.
