Guillem Balague examines what's going wrong for Luis Suarez at Barcelona this season.

Barcelona are top of La Liga - but it has been a difficult start to the season for their striker Luis Suarez. The former Liverpool player shone in his first three seasons in Spain but he has struggled this time around.

His frustration was summed up against Las Palmas in October when, in an empty stadium and with the game already won, he reacted to a missed chance by ripping his shirt in anger and storming down the tunnel.

He did get on the scoresheet over the weekend, finding the net with a close-range finish in the 2-2 draw with Celta Vigo on Saturday - but that was just his sixth goal of the season so far.

While many players would be happy with that return from 11 appearances, it puts Suarez on course to record his worst goals-per-game record since he moved to Barcelona in 2014.

So what are the reasons for his struggles? Well, one factor is his finishing. Suarez just hasn't been as clinical in front of goal as we've become used to seeing from him.
