The Blaugrana could have seized top spot in La Liga but were downed by David Moyes's side.

So far 2015 has been an interesting one for La Liga followers.

After Real Madrid's unbeaten streak finally came to an end, Barcelona fans were hoping that their side would take advantage to move to the top of the table.

However, Real Sociedad had other ideas, and after 90 minutes, the Blaugrana were reeling after a shock defeat on the road.

Not surprisingly, social media, as usual, reacted. However, what made the whole usual post-match Twitter buzz interesting was not just because Barcelona lost, but rather to whose side, as the hosts are now coached by none other than former Manchester United boss David Moyes.

Yes, that David Moyes, who was sacked before the end of the 2013/2014 Premier League campaign and saw Manchester United not only break a whole bunch of records all for the wrong reasons but also finish in 7th place. This means that the Red Devils are without Champions League--or even Europa League--football for the first time in many seasons.

But today, it was a victory for the ex-Everton boss, and even more so against one of the best sides in Europe. Check out how people reacted to the shock Blaugrana loss below.
