Relegation threatened Rayo Vallecano relied on the former Rams loanee to rescue a point against bottom side Real Betis with a stoppage-time equaliser.
It was considered quite a coup by then Derby manager Nigel Clough when he signed former Real Madrid striker Alberto Bueno on a season-long loan from Real Valladolid back in August 2010.
The season started well but a run of four wins in the last 26 league games saw them drop from fourth and dreaming of promotion, to nineteenth and the relief of not dropping down a division.
Despite that, Bueno became a firm favourite with the fans who were disappointed to see him leave at the end of the campaign and return to Spain.
The 25-year-old is now plying his trade with Vallecano who moved out of the La Liga relegation zone after a 2-2 draw at Betis. Bueno equalised after 51 minutes following the opening goal for the home side from former Wigan defender Antonio Amaya.
It looked as if the hosts were going to move off of the bottom when Joan Verdu came off the bench to put them back in front with ten minutes remaining, but Bueno had the final say in the first minute of injury-time when he slotted home which can be seen in the video below.
