A reported argument between Real Madrid star Cristiano Ronaldo and coach Jose Mourinho caps what has been a tumultuous season at the Bernabeu.

Defender Raul Albiol played down the alleged riff between Madrid’s biggest stars, as perhaps the most prominent club in the world struggles to live up to lofty expectations.

"Ronaldo and Mourinho are both winners. They only exchanged their opinions. What happened does in no way affect the rest of the team," Albiol said.

But sitting 18 points behind Barcelona at third place in La Liga, there’s no denying this has been a disappointing season for Real Madrid, and the club may start fresh with several moves.

Nuri Sahin’s loan to Borussia Dortmund on Jan. 11 was the first move and more may be coming.

Reports have surfaced that Kaka could make a return to AC Milan. The Brazilian’s agents met with Milan officials on Thursday, according to The Guardian. Kaka played six seasons and scored 70 goals while at San Siro, and hasn’t had as big an impact for Mourinho’s side as many anticipated.

Then there is Luka Modric, who just recently joined Madrid last August, but now may be returning to London. The Sun reported Chelsea are prepping a £22 million fee to bring the Croatian playmaker to Stamford Bridge.

FIFA Ballon D’Or finalist Ronaldo has been tied to several clubs but there has been no serious movement on that front. Paris Saint-Germain and their free spending ways over the past year had reported interest in the Portuguese star, as have his former club Manchester United.

However, there is no deal that appears close. Any club hoping to pry the 27-year-old from the Bernabeu will have to hand over at least a £90 million fee.

Madrid could also bring in some new talent, like striker Sergio Aguero from Manchester City, according to The Express. The 24-year-old Argentine has scored 31 goals since joining City in 2011, but could cost Madrid upwards of £45 million.
