Carvalho's Real Betis host a Real Madrid team that hasn't been at its best so far this season something the man born in Angola feels is down to the absence of Ronaldo's goals.
Five-time Ballon d'Or victor Cristiano Ronaldo could reunite with Zinedine Zidane at Juventus, according to journalist James Horncastle who believes the Serie A champions are looking at "moving to a more Galactico model".
"Carlo Ancelotti famously said: 'you can maybe say no to Real Madrid once, but saying no to them twice is not an option, because that train does not come through the station everyday'".
"It is hard to know [why he left], I do not know what happened, but I know how Cristiano is, he has an ambition the size of the world, he wants to always do things well and show that he is the best".
Former Real Madrid president Ramon Calderon has revealed the reason why Zinedine Zidane made a decision to leave the club.
"Zidane insisted on keeping Cristiano and selling Bale", Calderon told Spanish publication AS.
"Perez did the opposite to what Zidane had asked".
"I would not have sold him for €100 million".
Real Madrid head into Sunday's match fifth in La Liga, outside the Champions League places and ten points behind league leaders Barcelona.
