Right now, this is as big a problem as any in Barcelona minus the central defense.
Why? Because Andres Iniesta is still not at full strength just as La Blaugrana start the most pivotal part of their first half-season. With Sevilla, Benfica and Real Madrid all on deck, it is vital that Cesc Fabregas is in top form, whether as the uncontested started or a rotated player. All three matches are key.
To put it bluntly, Barça's No. 4 is not having a good season to this point. He has yet to score a goal in five appearances. What's more, his average of just one shot per game shows that he is rarely even getting himself in position to do so anyway.
Nor is the Spaniard helping his teammates. He has just two assists and both of those came in a 4-1 demolition of Getafe.
If this team is going to make it through the next three matches, they need more from their former La Masia prodigy.
Guardiola and Vilanova partially to blame
To be fair to Fabregas, his slow start is not entirely his fault. He has been shifted all over the front half of the pitch and continues to be played out of position.
Fans have long complained about his poor discipline, patience and positional awareness, but perhaps it is time to accept that Cesc Fabregas isn't the second coming of Xavi OR Iniesta, after all.
In all truth, the most ideal place for him to play for Barcelona in their current 4-3-3 is as a false 9, the same role he played for Spain.
Unfortunately for Fabregas, that role is currently occupied by the best player in football, Lionel Messi. There is no chance of him taking the reins there.
Change is needed, but not just from Fabregas
Rather than continuing to try and use Fabregas as a winger or having him get lost in Barcelona's complicated midfield, it's time to use him where he is more comfortable and where he is most useful.
That means a potential change in formation, which leads me to my next point.
