Mario Melero López waved for an inexistent offside from Luis Suarez
The Uruguayan finished but the goal was stricken from the records unfairly
After the controversial refereeing of Iglesias Villanueva at Mestalla, Barcelona have now had trouble with Melero Lopez at Camp Nou.
In the 27th minute Messi played in Luis Suarez, who was one-on-one with Ruben Blanco and finished well. However the goalkeeper did not move because the official had flagged the striker offside.
The linesman thought Suarez was ahead of the last defender but Jozabed on Celta's left flank played Suarez onside.
