Barcelona were held to a 1-1 draw at Valencia in a highly controversial game. The Catalan side had the ball behind the line in the first half but the referees failed to spot it and denied Messi a clean goal.Rodrigo then gave Valencia the lead in the 60th minute. It took a screamer from Jordi Alba for the league leaders to equalise and go home with a point.Here's how twitter reacted:La Liga has the worst referee's in the world... pic.twitter.com/EvQ5nKxGxq— Troll Football (@TrollFootball) November 26, 2017Barça lost La Liga last season because of this.Now they do it again pic.twitter.com/mkWoAR0uiJ— Leo Messi (@messi10stats) November 26, 2017How the La Liga referee's saw the goal last night... pic.twitter.com/0cKUCut3Gc— Football Expose (@FootballExpose) November 27, 2017How come Spain does not have goal line technology yet? pic.twitter.com/Kowxf0Nu4a— Troll Football (@TrollFootball) November 26, 2017The referee in the Valencia vs Barcelona match pic.twitter.com/NTg6BCGMzS— Footy Humour (@FootyHumour) November 26, 2017Barcelona fans complaining about referee is like Salman Khan complaining about scripts in bollywood movies.— T€JA$ (@MadristaSrkian) November 27, 2017The referee has ridiculed Spanish football. Is it a decision to punish Barcelona or human error, time will tell.— BARCA_BOY ??? (@Moshkom) November 26, 2017dear @LaLiga The referee who leads Valencia's VS Barcelona match has done a stupidity. The referee was immediately fired.

What a time to be alive— . (@iamlasbrey) November 26, 2017Mad that they don’t have goal-line technology in La Liga. Think they’ll be revisiting the debate after Messi’s goal was ruled not to have crossed the line when it clearly did.— Gary Lineker (@GaryLineker) November 26, 2017
