Gerard Piqué labelled Real Madrid's win at Elche a "comedy" after Cristiano Ronaldo converted a controversial last-minute penalty.
The Barcelona defender aired his dismay at the result following referee César Muñiz's decision to give Madrid a 96th minute penalty with the scoreline at 1-1.
Madrid defender Pepe appeared to tug Carlos Sánchez's shirt but Muñiz awarded the Portuguese a penalty. Sánchez was sent off after the final whistle for remonstrating with Muñiz.
Piqué tweeted: "Watching a comedy on Canal + Liga," referring to the Spanish television station which broadcast Madrid's match.
Viendo una película de humor por el Canal + Liga.. Siempre va bien a estas horas de la noche!— Gerard Piqué (@3gerardpique) September 25, 2013
The Catalan's post has been retweeted by over 49,000 users on the social networking site, at the time of writing.
Amusingly, Madrid defender Alvaro Arbeloa tweeted a picture of him with teammates after the game with the caption: "It’s nice to see some people swapping the theatre for a bit of cinema."
Muy contentos con los 3 puntos! Me alegro de que algunos cambien el teatro por el cine, eso siempre esta bien! pic.twitter.com/a1HR3pri8G— Álvaro Arbeloa (@aarbeloa17) September 25, 2013
Ronaldo's winner was his second having earlier struck a free-kick, as Madrid remain two points behind Barcelona.
Barça beat Real Sociedad 4-1 on Tuesday night to maintain their 100% Primera Liga record.
