Cellabos left the Estadio Benito Villamarín to join Zinedine Zidane’s men this summer and Boudebouz has been compared as the perfect replacement for the 21-year-old Spanish midfielder.
Real Betis kick off their La Liga campaign with a visit to the Camp Nou for their opening fixture against Barcelona on August 20.
“Ceballos is a great player, you need to be to sign for Real Madrid,” Boudebouz told Football Espana.
“He has a lot of quality but so do I and I want to make the difference for Betis in that position, but Ceballos is Ceballos and I am Boudebouz – we are different players.
“I like to be the axis of the team, playing centrally and helping to influence the game as much as possible; if the manager wants to play me wide then of course I will do it, I just love playing football.
“Betis are a huge club who are very significant in Spain and from pre season I can see they like to play stylish football, so I will fit right in.
“I spoke to Aissa Mandi and Jonas Martin and they both recommended here and that made up my mind, I had no doubts.
“The Spanish league is very technical so I believe I can settle in quickly.”
