Racing Santander have been plunged further into relegation trouble after a 3-0 defeat at home to Sevilla.
The visitors dominated from the first whistle as Gary Medel flashed his drive wide after 16 minutes.
Sevilla came even closer on 34 minutes when Alvaro Negredo saw his shot well saved by Mario Fernandez.
However, they were rewarded for their efforts soon after as Jesus Navas found the net to give his side the lead.
It took the away side only seven minutes into the second half to extend their advantage when Manu converted.
Racing's evening got worse with 10 minutes to play thanks to Pape Diop's straight red card for a reckless challenge.
The win was sealed in injury time when Manu bagged his second goal of the match.
