Luis Suarez says his debut against Real is because of a reason.

​Luis Suarez believes it was written in the stars for him to make his Barcelona debut against Real Madrid.
The Uruguay star is in line to make his long-awaited Barca bow at the Santiago Bernabeu on October 25 – a day after his four-month ban expires.
Suarez looked sharp in his country's friendly match against Oman on Monday, scoring twice in a comfortable 3-0 victory.
The former Liverpool man has now set his sights firmly on El Clasico – and feels destiny has decreed that he will debut for Barca at the home of their fiercest rivals Real.
“It's a huge coincidence but I'm looking forward to the experience,” Suarez told Barca Magazine.
“You know, I'm the kind of person who believes that things happen for a reason, and of all 19 teams in the league, it's precisely against Real Madrid at the Bernabeu that I'll make my comeback.”
“There must be a reason.”
Suarez's first UEFA Champions League appearance for Barca is set to come on November 5 at Ajax – a club he captained and scored 111 goals in 159 appearances for prior to moving to Liverpool in January 2011.
And, much like the fact his bow for Barca will come against Real, Suarez believes it is fate that he will play against Ajax this season.
“There are so many coincidences – and in Amsterdam of all places!” he added.
“To go back there after so much time and to return in the Champions League against the first team I played the Champions League with, for the team I have dreamed of all my life, which is Barcelona – yes, it's destiny again”.
“It will be a very special game for me, to meet again with all the people at the club, and the fans. I love all of that.”
Well i think, the reason for his El Clasico debut is to Win the match for Barca, while that against Ajax is to prove to them that they made a huge mistake by selling him.
