Jose Mourinho has no desire to finish second in any competition, and Real Madrid may have a busy summer with some major changes as perhaps the most prominent club in the world attempts to strengthen its already dominant squad.

Several high-profile names have been linked by British publication in transfer speculation to and from Real Madrid in February.

Cristiano Ronaldo, who has been subjected to some jeers from supporters at Santiago Bernabeu this season, may have interest in returning to England. The Express linked the Portuguese star to three Premier League clubs: Chelsea, Manchester City, and his former club Manchester United.

It would be fascinating to see what Ronaldo's valuation would be at age 27. In the summer of 2009, Manchester United received an unconditional offer of £80 million from Real Madrid.

According to Daily Mail, Real Madrid are interested in Sergio Aguero and plan on adding the Manchester City forward by sending Gonzalo Higuain to Chelsea this summer. Aguero arrived at City this past summer at a transfer fee of £38 million. The Argentine has excelled at City, and would likely command a very large offer.

Higuain, meanwhile, has not been in excellent form this season, and the 24-year-old may need a change of scenery to get back on track. He likely will command considerably less than Aguero, but Real Madrid have deep pockets and shouldn't have a problem making up the difference between transfer fees.

While Real Madrid appreciate established talent, Los Galacticos are always on the lookout for burgeoning stars, as well. Eden Hazard, who has been linked with Arsenal for about a year, and more recently Tottenham, is considered a target of both Real Madrid and Barcelona. The 21-year-old Belgian may not fit well in a rather over-crowded Real Madrid midfield, but the future of mainstay Kaka is somewhat in doubt, and Mourinho may lean towards a fresh face at Santiago Bernabeu.

The Belgian playmaker is rated at about £30 million, and Metro reported earlier in February that Tottenham appear to be the frontrunner.

How much Real Madrid are interested in a roster shakeup will probably determine the fate of Ronaldo, Aguero, and others, and that may have a lot to with how the rest of the Champions League season unfolds.

Mourinho's squad is running away with La Liga, but managed only a draw in the Round of 16 in Champions League play against CSKA Moscow on Feb. 21.
