​Barcelona will face ​Real Madrid in this season's first El Clasico in ​La Liga on December 18, a date which is just ​one week away, and Lionel Messi believes that Zinedine Zidane's men will be in good shape at the Camp Nou.

As reported by ​Marca, while speaking about the game in what can be called as an early buildup to the biggest club game on the planet, Messi said during the presentation of his new Adidas Nemesis 19 boots, "I expect a very strong Madrid."

He continued, "They are very decent in these games. They are special matches, no matter how one or the other comes into it. We are both in good form, but they are moments [where the form book goes out the window]."

Furthermore, Messi also spoke about what Barcelona's Champions League ambition should be as he said, "We must start from scratch because it is a new year, a new competition. We learn from the past, from mistakes, and focus on the present. It would be a mistake to fall into that [trap] again."

Finally, talking about the level of competition in La Liga increasing year after year, Messi concluded, "It is not just this year; you can notice it for several years now. Everything is more even - anyone beats anyone. It is difficult to play as an away team because the hosts have become very strong. That makes everything more complicated. Everything is more even."
