Real Madrid are reportedly targeting several English Premier League superstars, which could signal the end of the Cristiano Ronaldo era at Bernabeu.

According to The Sun UK, Real Madrid are planning to spend £250 million this summer to acquire Premier League targets. Los Blancos were handed a ban for the next two transfer windows but could be allowed to make moves this summer, while waiting for the result of their appeal.

The report revealed that Real Madrid are eyeing Chelsea star Eden Hazard, who is on top of their list of possible signings. Aside from Hazard, Manchester City star Sergio Aguero and Manchester United goalkeeper David De Gea are also on their radar.

And if they successfully secure the services of their targets, Real Madrid could begin selling valuable assets. Sources told The Sun UK that Gareth Bale's place at Bernabeu is safe, but Ronaldo could find himself moving to another club after the season. Ronaldo might be sold to Paris St-Germain for £100 million, the report added.

PSG defender Thiago Silva believes the rumored move is not a long shot, and they will gladly welcome the Portugal international because he thinks Ronaldo will be a difference maker.

"A move for Cristiano Ronaldo? He is a player who makes the difference for Real Madrid. If he would be open to joining PSG, to help us and to make the difference for PSG," Silva told reporters.

However, the Ronaldo-to-PSG rumors should be taken with a grain of salt until both clubs admit that they are open to striking the lucrative deal. Real Madrid manager Zinedine Zidane insisted that Ronaldo is bound to stay at Bernabeu, denying the transfer rumors involving their superstar forward.

"Cristiano Ronaldo is non-transferable," Zidane told reporters earlier this month. "He's the soul of this team. While he's here, he won't leave. Cristiano will play on the wings, how he's most comfortable. I won't tell him much. I want him to be happy."

Ronaldo, who moved to Real Madrid from Manchester United in 2012, also appears to be happy at Bernabeu, especially after the club appointed Zidane, who took over after Real Madrid axed Rafael Benitez following their disappointing start this season.

Following their 5-1 win against Sporting Gijon on Sunday, Ronaldo had nothing but praises for Zidane, saying that Real Madrid players are happy with their new manager's performance.

"Personally I have more feeling for Zizou, but don't ask me why. He has an empathy with the players and I am very happy and excited," Ronaldo said via Mirror UK. "It's an interesting moment for me and the players. We are in good shape and working hard."
