Sandler’s injury could remove the defender NEC can least afford to lose against Olympiacos | OneFootball

NEC Nijmegen’s defeat to Sevilla initially appeared to leave one notable defensive concern. Further post-match reporting revealed a potentially more important one.

Philippe Sandler, the central defender around whom much of NEC’s back line is organized, did not leave after half an hour as part of Dick Schreuder’s extensive preseason rotation. The coach confirmed that Sandler had felt discomfort and was withdrawn as a precautionary or necessary response rather than according to the original plan.

The severity remains unknown. The timing is unmistakably problematic.

NEC visit the Georgios Karaiskakis Stadium on Tuesday with an already compressed group of established defenders. Sandler’s availability could determine not only who starts, but how aggressively Schreuder is willing to defend.

Why Sandler matters structurally

Sandler is more than an individual marker or aerial defender.

He provides composure in the first phase of possession and helps NEC progress the ball when opponents press high. That is particularly relevant against José Luis Mendilibar’s Olympiacos, whose forwards will attempt to force the Dutch side into rushed decisions close to its own penalty area.

With Sandler available, NEC have a defender comfortable enough to receive under pressure, delay until a passing lane opens and play through or around the first line.

Without him, the side may become more dependent on:

Each solution carries a cost. Bringing midfielders deeper can weaken NEC between the lines. Playing long can expose them to Olympiacos’ pressure on second balls. Forcing play wide can allow Gelson Martins or Jota Silva to trap the full-back against the sideline.

El Kaabi becomes a more difficult problem

Ayoub El Kaabi’s movement is demanding even for a settled defence.

He rarely remains fixed against one centre-back. He shifts across the line, threatens the space behind, attacks the front post and initiates Olympiacos’ pressure with curved runs designed to close one passing option while pursuing another.

A reorganized NEC defence would need to coordinate those movements without its most experienced available central reference.

Olympiacos should test that coordination immediately through:

The objective would not simply be to isolate a replacement. It would be to force the entire back line into decisions before its communication becomes comfortable.

NEC’s defensive depth is becoming a genuine tactical issue

Perr Schuurs was already unavailable and omitted from the European list. Yassin Moslih then left the Sevilla friendly after entering as a substitute. Sandler’s problem adds another layer of uncertainty.

UEFA’s published squad still lists Sandler and Moslih, meaning either could participate if medically cleared. Registration is not evidence of fitness.

Should Sandler be ruled out, Schreuder could turn to some combination of:

The options exist, but several combinations would either reduce pace, weaken buildup or require positional adaptation.

That matters because Olympiacos can attack NEC in contrasting ways. El Kaabi offers direct depth, Gelson can run at defenders, and Gustavo Sá or Chiquinho can receive in the spaces opened when a centre-back steps forward.

A defence assembled around compromises may solve one problem while creating another.

Olympiacos should increase the physical cost of the first leg

Even if Sandler recovers sufficiently to start, his early withdrawal gives Olympiacos a reason to test him.

That does not mean targeting an injured player recklessly. It means making every defensive action demanding:

A player carrying discomfort may cope with isolated duels but struggle as the cumulative workload increases.

Karaiskakis can add another layer. An intense opening period would prevent NEC from easing Sandler—or any replacement—into the match.

The uncertainty affects Schreuder’s wider selection

The injury decision cannot be isolated from NEC’s attacking plan.

A less secure defence may encourage Schreuder to add another conservative midfielder, reducing the number of creators around Dušan Tadić and Tjaronn Chery. Alternatively, he may attempt to protect the defence through possession, asking his technical players to control the ball for longer stretches.

Both approaches influence the tie.

A more defensive midfield may make NEC harder to break down but less dangerous in transition. A possession-heavy plan may expose them directly to Olympiacos’ press.

Sandler’s fitness therefore affects not merely one position. It may alter the balance of the entire lineup.

The medical update remains decisive

No authoritative report has yet provided a diagnosis.

Sandler may have been removed at the first sign of discomfort precisely because the match was a friendly and NEC did not want to take unnecessary risks. He may train normally before Tuesday.

The confirmed information is narrower: he experienced a problem, Schreuder did not intend to substitute him so early, and NEC must now evaluate whether their defensive leader can play in Piraeus.

For Olympiacos, the preparation should cover both possibilities.
