According to Sport, after a three-week international break, Barcelona faces a major hidden challenge: numerous international players are severely fatigued both physically and mentally, and the risk of injury has increased sharply. This is an issue that must be prioritized by Flick.

Although UEFA restructured the Nations League format this year with the goal of reducing player workload and avoiding excessive strain, the real-world effect has fallen short of expectations. Many focus only on the number of international matches but overlook the hidden toll on players: frequent long-haul flights, constant travel between different cities, time zone and climate changes, disrupted diets and routines, frequent changes of training facilities, and most critically—complete disruption to clubs' systematic training rhythms.

International schedule is excessive: 4 matches in 11 days, scarcely any proper training time.

Take Spain's national team as an example. They played 4 matches in just 11 days, from September 26 to October 6, averaging less than one match every four days with no complete rest days. During this period, the team also made four long-haul trips, physically and mentally draining the players.

Moreover, such a congested schedule makes normal training impossible: the day after a match is reserved for rest and recovery, and the day before a match involves only simple tactical drills at low intensity. Between any two matches, players never get a single complete high-intensity training session. Even when simple training occurs, it can only focus on tactical adjustments and cannot push players physically, since they have just played consecutive high-intensity matches and are already overextended.

To summarize this international break situation: three fragmented training sessions, rushed travel, and back-to-back matches with high intensity. It is unsurprising that injuries occur during international duty; the root causes are an overstuffed schedule and exhausting travel, leaving players with no accumulated physical reserves and training that is entirely uncoordinated.

With only three days to recover, Barcelona players cannot fully recuperate.

Most of Barcelona's international players return to the club on Wednesday, leaving only a short three days before the weekend LaLiga match.

They cannot train on their return day, having just completed long-haul flights and played a match the previous evening; Thursday allows for one normal full team training session; Friday, the day before the match, requires reduced training intensity.

However, before this, the players have endured an exhausting 11-day schedule: psychological pressure from consecutive commitments, extraordinary physical exertion, and no systematic training foundation. Under these circumstances, the injury risk for players is maximized.

The safest solution is actually straightforward: avoid playing if possible, use substitutes extensively, and if they must play, strictly limit their time on the pitch, prioritize player health, and reduce injury risk.

Barcelona lacks depth; Flick is forced to take risks with his players.

Priority should go to players who did not have international duty or reserves who saw minimal playing time for their national teams. However, Barcelona cannot do this.

Most of the squad's key players are regular starters for their respective national teams, and even young U21 players had full playing time for their national teams, meaning nearly everyone is overextended. This forces Flick to field fatigued players in the starting lineup.

Flick's main task now is careful energy management and allocation: if the match is going well, attempt to substitute out the players most heavily used by their national teams. But this is not easy; there are no weak teams in LaLiga, and Barcelona's next opponent, Getafe, is highly competitive. To win, Barcelona must give their all, and Flick can only balance winning with protecting his players, taking calculated risks.

Current stage: Recovery takes priority over training.

During the three-day preparation period after international players return, everything must be subordinated to recovery. Training volume must be reduced to fully alleviate the accumulated muscle fatigue and mental exhaustion on players. At the same time, diet and hydration must be specially tailored to help players recover quickly.

The team's physiotherapy staff's injury prevention work and sufficient sleep for players are critical. It might even be beneficial to give players two brief days off to spend with family and completely remove match pressure, returning for full team training on Friday for better results.

Klopp's coaching model, which involves building a large squad of around 40 players for free rotation and distributing physical demands, would be well-suited to this situation. However, this model also has drawbacks, as it can affect team performance, and therefore remains controversial.

If El Clásico were this week, the consequences would be unimaginable.

Imagine if this round's match were El Clásico between Barcelona and Real Madrid; the problem would completely explode. The intensity and psychological pressure of a derby are already at their peak, and fatigued players would see their injury risk doubled, while performance quality would plummet sharply, with far more errors and nervous mistakes on the pitch.

Ultimately, to maintain peak performance in football, you need consistent, stable training plus sufficient physical reserves. However, the congested international schedule and frequent travel directly disrupt this rhythm. Players returning to their clubs exhausted, underperforming, and vulnerable to injury represents Barcelona's biggest hidden problem at this stage.
