On September 4, Paris Saint-Germain released the squad list through official channels for the Ligue 1 third-round match against Monaco. One name's absence immediately became a talking point: Lucas Digne.
He is not a player recovering from injury, nor is he a new signing who has yet to complete registration. He returned from Aston Villa on August 9 for €7 million, with all procedures completed and registration finalized, yet he has not played a single minute of official football in the first three Ligue 1 rounds.
More notably, PSG's regular starting left-back Nuno Mendes was also unavailable for this round. Head coach Luis Enrique's solution was not to include Digne in the squad, but instead to use center-back Lucas Hernandez as a makeshift left-back.

A position that was strengthened with spending money still did not see the new signing used when the starter was absent, which itself became a signal requiring explanation. PSG team reporter Djamel confirmed on the same day that Digne's omission was “not because of injury, but a decision made by Enrique.”
Before this, internal information had emerged from L'Equipe suggesting that the club believed Digne had encountered difficulties adapting to Enrique's tactical system and needed to show stronger competitive desire. However, these reports remain second-hand information, and PSG has never publicly commented on the matter.
Viewed within a longer timeline, the contrast becomes clearer. Last season at Aston Villa, Digne made 28 Premier League appearances, including 9 starts, provided 5 assists, and recorded an average season rating of 6.73, establishing himself as a reliable rotation-level left-back in the Premier League.
He joined Villa from Everton for €30 million in 2022 and returned quickly after suffering an ankle injury in October 2025, with no public reports showing a major decline in his form. His return to Paris this summer was originally seen as a precise reinforcement for the left-back position, but less than a month after joining, Digne was left out of both friendly and competitive matches.

From a performance data perspective, Digne's displays in PSG's first three pre-season friendlies were indeed below expectations: 0.7 tackles per game, only a 42% success rate in duels, and no assists. However, the friendly sample size was very small, and opponent strength and tactical demands differ fundamentally from official Ligue 1 matches, so it cannot directly prove that he is unable to play as a Ligue 1 left-back.
A fact worth comparing is that during his first spell at PSG in the 2014-15 season, Digne made 15 Ligue 1 appearances and recorded one assist. The team's system was completely different from today, but it at least shows he is not a player naturally incompatible with PSG's tactics.
The real issue may not be ability, but whether Enrique's current functional requirements for the left-back position are mismatched with Digne's technical characteristics.
Enrique's preference for wing players has already become visible this season. Achraf Hakimi has started continuously on the right, while on the left, when Mendes was unavailable, Enrique chose a center-back as a substitute rather than using Digne. This suggests that in his framework, the left-back role involves not only defending and crossing, but may also require more complex positioning and forward movements.
Hernandez has the physical attributes and tactical discipline to fill in, while Digne did not show similar qualities in pre-season matches, at least according to currently available public data. However, this remains speculation because Enrique has never publicly explained his specific tactical definition of the left-back role.

For Digne, the current situation is clear: he is outside the squad list, and his competitor is not another left-back but a center-back who is not naturally a player for that position. Other PSG summer signings, including Maghnes Akliouche and Ferran Torres, have already received appearances in the first two Ligue 1 rounds, with Torres even scoring twice against Rennes in the opening round.
Digne is the only new signing who has been excluded from the official squad for three consecutive rounds.
At the same time, the reason for Nuno Mendes' absence has still not been explained by PSG officially. If his absence is short-term, Digne's situation still has room to change; if the absence lasts longer, the signal of Digne being continuously sidelined will become stronger. Currently, no official information can answer this question.
From a rules perspective, PSG has every right to make this decision. Ligue 1 has no requirement forcing new signings to play, and squad lists have no strict positional quotas. Enrique, as head coach, has full authority over selection decisions. There is currently no public sign of intervention from club executives.

This means Digne's short-term future almost entirely depends on his training performances and Enrique's judgment, rather than any external force.
The confirmed boundaries of the situation are: Digne's omission from the squad was an active decision by Enrique, not due to injury; Digne's pre-season data was poor but based on a limited sample; PSG paid €7 million for him and completed all registration procedures; the specific reason for Mendes' absence has not been made public.
What cannot be confirmed is whether Digne has an undisclosed physical issue, whether there are deeper communication problems between him and Enrique, and whether this exclusion is a short-term adjustment or a long-term role decision.
The next real test is already on the schedule. PSG hosted Monaco in the early hours of September 5, with Hernandez playing as a makeshift left-back becoming one of the match's talking points. Around September 12, PSG will announce the Ligue 1 fourth-round squad list, which will be the first official window to observe whether Digne's situation changes.

If he is absent from the squad for a fourth consecutive round, then the term “being sidelined” will no longer only be a media judgment, but a fact that can be directly verified through appearance data.
Until then, Digne has limited options. He needs to return to Enrique's attention through training, while Enrique needs to decide whether a new signing who has yet to prove himself is worth the risk when no natural left-back is available. €7 million is not an investment a club would easily abandon, but at the competitive level, a transfer fee is never a guarantee of playing time. This silent standoff over selection decisions still has no answer.
