Hansi Flick arrived at Barça just over a year ago and quickly revolutionized the team and the fans. The culés saw him as the new leader of the Catalan side and he quickly showed that he knew what he was doing. In fact, the club from the City of Counts has once again become one of the best in the world.
With stars like Lamine Yamal, Pedri, and Pau Cubarsí, Hansi Flick has made the entire continent respect Barça again. Little by little, Joan Laporta is managing to leave the financial problems in the past and, although there are still some issues, good work is being done. Now, the coach is thinking about a major signing and it's possible that he has conveyed this to Deco.

Deco and Joan Laporta's management
Deco and Joan Laporta have been two of the most criticized people around Barça in recent years due to their management. Although some decisions have been poor, both have had major successes, such as betting on Hansi Flick. The coach arrived because the top brass trusted he would revive the team.
Joan Laporta has had to deal with a very delicate situation and the reality is that, little by little, he has managed to climb out of the deep hole the club was in. Meanwhile, Deco has managed to get top players to sign for Barça with more than considerable salaries. In addition, major sponsors have been secured and key contracts, such as Nike's, have been renewed.
One of the biggest problems Barça (and most teams) face is injuries, which are always lurking. Right now, the Catalan side has problems at left back, since Alejandro Balde is injured. Although Gerard Martín is available, Hansi Flick could take the opportunity to secure a major signing.
Alejandro Balde's replacement is in Deco's hands
Although Gerard Martín can fill that position without issue, Barça would definitely benefit from another high-level fullback. Jofre Torrents is still a bit inexperienced and an injury to Gerard would be a serious problem. According to Hansi Flick, Deco could explore signing Nico Schlotterbeck, the Borussia Dortmund defender.
Nico Schlotterbeck has a market value of 40 million and can play as a center back and as a left back. Although it's likely that Deco will stay on the sidelines for now, Barça could knock on Nico's door during the next transfer window.
