#2 Gives Real Madrid much-needed squad depth
The right-back position was probably the weakest area in the Real Madrid squad last season because they were left light after the departure of Danilo. Carvajal's injury at the start of last season highlighted that with youngster Achraf Hakimi having to step up as well as Nacho being used in an unfamiliar position.
Both performed well considering the circumstances, but bringing in Odriozola is a better solution.
This transfer ensures they have depth in every position, which means they can compete on all fronts. Zidane was certainly successful because he won three consecutive Champions League titles as well as a league title. However, the title defence last season was abject.
Lopetegui's ideas should avoid a repeat of that in the league if he is able to successfully implement them, and having squad depth should ensure that they can maintain consistency until the end of the season for the crucial Champions League matches.
As mentioned above, Carvajal was out numerous times during the season such as the hamstring injury he picked up in the Champions League final, which nearly ruled him out of the World Cup. He has also suffered a number of injuries over the past few seasons, so having a talented back-up in his position is crucial.
Odriozola's comfort in attacking areas also provides Lopetegui with the option of playing a back three because he and Marcelo would certainly be comfortable playing as wing-backs. Therefore, Real have plenty of tactical versatility for the upcoming season, which is only likely to have increased with the departure of main man Cristiano Ronaldo.
