What are Real Madrid's biggest needs in the upcoming transfer window?

After winning a major trophy, especially like la Decima, an aurora of invincibility often sets in for a club. This Real Madrid team will likely be no different, but in order to avoid a hangover slipping into next season, what can Madrid do to improve their current squad? This is no easy question, as the first team boasts an abundance of world-class talent. In fact, it is rather difficult to point to a major weakness for this squad. It would be foolish to say that Madrid need a player of Luis Suarez's caliber to remain the best club in the world-but what type of player do they need to ensure that?

Madrid's most evident weakness would likely be pinpointed as a lack of depth at striker. Karim Benzema has proven that he is an absolute magician on the football field, with his incredible ball control and hold up play. However, Benz has been known to squander chances and is often not fully fit. So who can Real Madrid turn to? As referenced earlier, Suarez is a ludicrous demand to fill the need. While the Uruguayan is definitely an incredible player- his price tag and antics should rule him out. Next, the most logical fit should be Alvaro Morata. However, he has yet to prove himself with the first team despite being given ample opportunity. Another interesting option could be Jese Rodriguez. Before his injury, the youngster was adapting perfectly well to playing in the number 9 role- however it is a misuse of his explosive pace if he is not on the wings. So who will Madrid target? Would a player like Mario Mandzukic be content with a secondary role in Madrid? Only time will tell.

In addition to needing a second, class striker, Madrid may also look to strengthen their midfield. The need here is much less apparent, but it did show is Lisbon. Is Asier Illarramendi ready to fill Xabi's shoes? If so he will need to greatly improve this summer. The promising young Brazilian, Casemiro, is in desperate need of consistent game time to improve his game and should be loaned for the upcoming year. And what is the fate of Sami Khedira? Real Madrid will reportedly extend the German's contract, and having a player of his caliber available will be a great boost to the midfield when he is fully fit next season. So therefore, it doesn't appear that Real have any needs in the midfield- but are they suited to make any purchases?

Finally, there have been rumblings for some time that a new left back will be signed- particularly one Alberto Moreno. There obviously is not a need for a left back, given that Real have two of the best left backs in the world already. However, will the ever-present rumors linking Coentrao and Marcelo to their exits finally come to fruition? Hopefully not. These two proved this year that their contrasting playing styles allow Real Madrid to have the most dynamic back line in world football- as exhibited by their rotation in the Champions League Final. So again, while there is no need, a move could still be made.

If Real Madrid want to become the first side to ever repeat as winners of the Champions League, player movement will play a crucial role. But which players will be on the move? Let us know your thoughts!
