It was a tumultuous day in Barcelona.Sunday's clash at the Camp Nou between Barcelona and Las Palmas was initially postponed, as safety concerns related to the Catalonian independence referendum caused chaos in the city.However, the decision was eventually reversed and the game went ahead, although it was done so behind closed doors.There was a strange atmosphere present in the Camp Nou considering the 99,000 capacity stadium was virtually empty, but Barcelona's players were not fazed as they eventually ran out 3-0 winners.It was not all straight forward for La Liga's leading team as Las Palmas held them to a goalless first half, but three second half goals, one from Sergio Busquets and a brace from Lionel Messi, gave the home side the victory.Whereas it was another great day for Lionel Messi, another Barcelona star is not enjoying his football as of late.Luis Suarez has not been at his imperious best in recent weeks, and his lack of goals is starting to become an issue for the Uruguayan striker.In his past eight starts, Barcelona have scored 18 goals, but the former Liverpool forward has only contributed two of them.And it looks as if Suarez's struggles in front of goal is starting to effect his confidence.Towards the end of today's game, Suarez had a golden opportunity to get on the score sheet, but he dragged his effort wide when one-on-one with the keeper.The Uruguyan completely lost his head after the miss, and in sheer anger he ripped his shirt.He then refused to come back onto the pitch and Barcelona were forced to see out the final few minutes with 10 men.You can watch the bizarre moment here: Barcelona fans were astonished by Suarez's actions on Twitter.You can read some of their tweets here:

With that win, Barcelona maintain their 100% record in La Liga having won all seven of their games so far this season.

However, the form of Luis Suarez is without doubt a concern and fans will be hoping he can rectify his shortage of goals sooner rather than later.
