Gerard Martín, Balde's substitute, has performed excellently every time Hansi Flick has required his presence. The full-back has played 41 official matches in which he has scored one goal and provided 6 assists. Although he doesn't have the necessary level to play for Barça, he has adapted perfectly.
Hansi Flick knows that, despite his efforts, Gerard Martín doesn't meet the minimum level necessary to compete for all the titles. Therefore, Joan Laporta, along with Deco, are active in the market looking for the best possible solution. Flick has requested the arrival of another full-back of higher level to compete with Balde.

Alejandro Grimaldo, the chosen one by Hansi Flick
Alejandro Grimaldo is a full-back who was raised in La Masia, but never debuted with the first team. He had to leave to seek his opportunity in European soccer, and he has already played in Portugal and Germany. After his time at Benfica, where he already stood out, he has thrived at Bayer Leverkusen under Xabi Alonso, becoming an undisputed starter.
In recent days, Alejandro Grimaldo has shown interest in Barça, who are already considering his signing, but also in Real Madrid. However, what seems clear is that it will be his last season at Bayer Leverkusen. Hansi Flick awaits him with open arms.
Alejandro Grimaldo would accept being Balde's substitute who, if injuries keep away, should be a very complete player needed by Hansi Flick. Additionally, this competition would improve the performance offered by Gerard Martín. A masterstroke by FC Barcelona.
What can Alejandro Grimaldo bring to FC Barcelona?
The figures of Alejandro Grimaldo in the last season with the German team leave no one indifferent: 4 goals and 13 assists playing as a left wing-back. Additionally, he was also a key piece in last year's double. It's clear that Grimaldo would be a very useful reinforcement for FC Barcelona.
Alejandro Grimaldo's offensive character makes him a very complete full-back who, if the team needs it, can also play as a winger. From FC Barcelona, they view his return favorably, as let's remember he was trained in La Masia several years ago. In any case, it's evident that the level Grimaldo can offer is far superior to that of Gerard Martín.
