Luis Suarez Will Be the Crucial Ingredient in Luis Enrique's Barcelona XI

Barcelona are in fine form in La Liga, with a 100 per cent record so far, but they still have much further to go and suspended striker Luis Suarez will be the final, crucial ingredient.

The Uruguayan hitman is out until October 25, when his ban for biting Giorgio Chiellini during the World Cup ends and could make a flying start against Real Madrid.

His ban expires the evening before the game and it would be bold, but a far from impossible move for Luis Enrique to throw him into the mix.

Suarez is training well and may get to play a few friendly games for Uruguay before the Clasico, which will get him in match shape.

His unique (Molotov) cocktail of unpredictable trickery, unbridled aggression and an incredible cutting edge is the sort of factor which decides high-pressure games like Real Madrid vs. Barcelona.

But whatever happens when the two sides meet, Suarez can prove to be the difference between them over the course of the season.

The Barcelona we have seen so far has a solid base but lacks star quality and incision going forward.

That's an odd thing to say, given that Lionel Messi is in the attack, but he's taken more of a creator's role since he scored twice against Elche on the opening day.

Messi set up Sandro Ramirez for the only goal of the game against Villarreal and laid on both of Neymar's this weekend against Athletic Bilbao.

He has been the best thing about Barcelona's attack so far this season, as you would expect. The supporting cast have impressed to differing degrees.

Munir El Haddadi started with a bang, netting a well-taken goal against Elche, but he was quiet against Villarreal. Against Athletic he was the centre of attention.

Munir wasted several chances, betraying his youth and inexperience, but also could have been awarded two penalties. Furthermore, he scored a goal which was unfairly ruled out for offside.

Far less impressive was Pedro, who couldn't offer much and hasn't at any other point of the season either.

Neymar came on, and as we know, struck twice as well as changing the momentum of the game and putting a lot of pressure on Athletic.

When fully fit, he is nailed on for the left-hand-side forward's position, which Pedro started in on Saturday. Suarez, meanwhile, will take the right-hand-side slot the other side of Messi.

Munir will probably play a few games for Barca B this season, combined with frequent first-team appearances.

The introduction of Suarez will give Barcelona a lot more incision and with his brilliant dribble technique and direct way of playing, they will look a lot more effective going forward.

At the back, things have been solid and the midfield also looks good too, with Ivan Rakitic slotting in nicely. A player like Suarez will thrive on Raktitic's clever through balls and raking passes.

Until Suarez returns, Luis Enrique's job is to fine-tune what he has available to him. That means settling on a defensive partnership, with Jeremy Mathieu and Javier Mascherano looking solid.

It means deciding which goalkeeper is selected, although with three clean sheets in three games and a 20-year record broken, according to SPORT, Claudio Bravo will be hard for Marc-Andre ter Stegen to displace.

It means reincorporating Neymar into the starting line-up, after two substitute appearances.

And it means making sure everything else is fixed in place for the day Suarez returns to first-team duty.
