Yamal did not fully participate with the team in the final training session. This was not a minor absence, as he was arranged to train separately. The reason was simple: he suffered a knock during training. Flick did not give a definitive answer, only saying casually that they would have to “see the situation on the day.” But everyone knows how much weight is hidden behind those words.

To be honest, seeing this scene was difficult. Yamal is only sixteen or seventeen years old, right? Yet he has already become one of the brightest stars at Barcelona and across European football. Moments like this show the club’s complicated feelings toward him—they cannot do without him, but they also fear he could get hurt. Is this dilemma only happening at Barcelona? Top clubs around the world are watching this youngster. Every touch he makes is valuable, and every drop of sweat draws the attention of countless people.
The start of the season has not been bad for Barcelona. The squad depth is sufficient, and the injury list is relatively manageable. But there is no room for early optimism, as the upcoming schedule will be demanding. Playing in both the league and European competitions, combined with Spain’s intense summer heat, and a 4 p.m. kickoff, will maximize the physical challenge. With temperatures expected to reach 34 degrees Celsius and strong sunlight, playing a full 90 minutes in such conditions would leave anyone gasping.
The choice Flick faces now can essentially be summed up in two words: short term and long term. Winning this match would allow Barcelona to gain a psychological advantage after the fourth round and seize an early position in the standings. But if Yamal is overused for this one match, what happens in the later European fixtures? What about difficult league matches ahead? Coaches have to calculate these factors countless times every day, often until it becomes exhausting.
The 24-player squad list will have to be reduced by one before the match. The number itself may not seem significant, but the message it sends is important: Flick has options. He does not need to insist on one starting lineup; he can rotate players and preserve energy in the heat. Squad depth is something that often goes unnoticed until a critical moment, when it becomes a lifeline.
If Yamal starts, Barcelona’s tactics would be clear—wing attacks, quick counterattacks, and solving problems through one-on-one situations. Yamal’s ability to carry the ball and deliver passes behind the defense is a major headache for opponents. But if he can only come off the bench or has limitations, Barcelona will need another approach: Gavi organizing in midfield, Jesus making runs, using possession to wear down the opponent while reducing Yamal’s running distance.
At this point, the hidden opponent of high temperatures must be mentioned. On a 34-degree pitch, players lose energy much faster than usual. Flick is likely to make substitutions earlier rather than waiting until after the 60th minute to react. Having the medical team ready on the sideline is standard practice, and details such as hydration and cooling are no longer minor matters in modern professional football.
The most intriguing part of this match is the psychological battle behind it. A win would boost Barcelona’s morale and put pressure on opponents in the standings. A loss or an unattractive performance would bring intense media scrutiny. Making decisions under this pressure requires careful consideration from any coach. Flick is not a manager who likes unnecessary risks; practicality is his trademark, and his approach to Yamal shows that.
What fans care about most is whether Yamal can start. But this question itself is somewhat difficult—a young player has suffered a knock; should he be sent onto the pitch? The answer was already contained in Flick’s words: it depends on the situation on the day. It may sound like a standard response, but it is the truth. Matches change quickly, and whoever can still make clear judgments ten minutes after kickoff gains an advantage.
What is the conservative option? Start Yamal but protect him appropriately in the second half by reducing his time in high-intensity battles. What about the rotation option? Leave him on the bench and bring him on only when the situation requires it. Neither choice is absolutely right or wrong; the key is how Flick weighs the options. In my view, the youngster needs protection, but not excessive protection. Appropriate challenges are also beneficial for his development.
The conditions of Gavi and Jesus are also worth watching. Gavi has struggled with injuries in recent years, and maintaining his current level of performance is already remarkable. Jesus is still adapting at Barcelona, and whether he can dominate in central areas will directly affect the team’s attacking patterns. Their performances, in a sense, will determine Yamal’s role on and off the pitch.
Ultimately, this match at Mestalla has already gone beyond the meaning of three points. It is a small test of Flick’s tenure at Barcelona and also a test of the club management’s policy on protecting young players. High temperatures, scheduling demands and injuries combined are enough to trouble any team.
Regardless of the final result, one thing is certain: Flick will use the squad’s depth to achieve stability. This is not conservatism, but a mature coaching approach. The season is still long, and Barcelona needs consistent output rather than brief flashes of success in one or two matches. Managing the health of every player may be the most important victory of this summer.
The heat at Mestalla has already begun to intensify, and Barcelona’s journey is only starting. Will Yamal start? What decision will Flick make? These questions will be answered on match day. But one thing is clear—this match is not just another game; it is a reflection of the direction of the season and deserves the attention of everyone following Barcelona.
