Known for his high-pressing, Red Bull-educated style and sharp tactical focus, 38-year-old German coach Jaissle has developed a reputation as one of the most highly-rated young bosses in top-level football - but his appointment is still a risk.
Whenever a manager takes charge of a major project, they naturally look to familiar faces - players who already understand things such as pressing triggers, defensive demands, and dressing room culture.
Once his appointment is rubber-stamped, it would be reasonable to expect Jaissle to recommend such personnel to the Newcastle hierarchy.
Seven players Newcastle might sign under Matthias Jaissle
Despite so far having had a summer in which they have been one of the Premier League's more active clubs in the market, Newcastle are still in need of targeted reinforcements throughout the side.
It is for that reason, the 'Jaissle effect' could be important during the final month of the summer window. Here are seven players who worked under Jaissle and fit Newcastle's squad requirements.
Nicolas Seiwald (Defensive Midfield)
Appearances under Jaissle: 91 (6 goals, 14 assists)
No outfield player featured more frequently for Jaissle during his trophy-laden tenure at Red Bull Salzburg than Austrian midfielder Nicolas Seiwald.
Functioning as the engine of Jaissle’s midfield diamond, Seiwald reigstered 91 appearances under the German, offering press-resistance and defensive coverage. Newcastle's midfield lacks depth in the holding role, making Seiwald a candidate to rejoin his former boss.
Gabri Veiga (Attacking Midfield)
Appearances under Jaissle: 66 (12 goals, 10 assists)
After making the switch from LaLiga to Al-Ahli, Spanish playmaker Gabri Veiga began working under Jaissle.
Across 66 matches together in Saudi Arabia, Veiga contributed 12 goals and 10 assists before joining FC Porto last summer. With Newcastle seeking a goal-scoring midfielder capable of unlocking low blocks, Jaissle could provide 24-year-old Veiga with the platform for a top-five league reboot.
Oumar Solet (Centre-Back)
Appearances under Jaissle: 66 (2 goals, 4 assists)
Jaissle’s aggressive, high-line defence at Red Bull Salzburg relied heavily on recovery speed and composure of his central defenders, of which Oumar Solet was one.
Featuring 66 times under Jaissle, Solet knows how to play in his backline that routinely dominated domestically and competed admirably in the Champions League. With Newcastle needing long-term athleticism and ball-playing quality at centre-back, Solet fits the tactical profile.
Amar Dedic (Right-Back)
Appearances under Jaissle: 52 (4 goals, 6 assists)
Bosnian full-back Amar Dedic enjoyed his breakout under Jaissle at Salzburg, making 52 appearances and contributing direct to 10 goals from right-back.
His ability to invert into midfield or overlap down the right aligns with Jaissle’s tactical flexibility. Given Newcastle's need to refresh their options at full-back after Kieran Trippier's exit and Tino Livramento's persistent injuries, Dedic could be an option given he already knows the manager's demands.
Mohamed Camara (Defensive Midfield)
Appearances under Jaissle: 43 (1 goal, 5 assists)
Before earning a move to AS Monaco, Malian midfield enforcer Mohamed Camara was the defensive anchor of Jaissle’s 2021/22 domestic double-winning Salzburg side.
Playing 43 games under the soon-to-be-named Newcastle coach, Camara demonstrated excellent ball-winning capabilities as well as decent ability in possession. His tenacity in duel-heavy games would instantly bolster Newcastle's stability in the middle of the park, which is in need of some experience and steel.
Enzo Millot (Attacking Midfield)
Appearances under Jaissle: 40 (9 goals, 7 assists)
French midfielder Enzo Millot worked closely with Jaissle at Al-Ahli, making 40 appearances and registering 16 direct goal contributions.
Millot’s tactical nous, exhibited whilst still in Ligue 1, and pressing energy make him a coach's dream in a high-intensity transitional system. Newcastle's squad would benefit from his quality between the lines.
Karim Konate (Centre-Forward)
Appearances under Jaissle: 10 (5 goals, 2 assists)
Ivorian striker Karim Konate made his initial top-flight breakthrough under Jaissle at Salzburg, netting 5 goals and laying on 2 assists in just 10 appearances.
Despite that limited sample size before the manager's departure, Konate showed good goalscoring efficiency that foreshadowed his more recent rise as a top striking talent in a mid-tier European league.
While bringing in Jaissle’s trusted former players makes sense on paper, fans would be wise to temper expectations of an instant transformation.
Moving on from almost five years of stability under Eddie Howe marks a significant structural shift, leaving a dressing room very much in a state of flux and notably lacking in natural on-pitch leadership. That will be a responsibility that Jaissle himself must bear while adapting to the demands of English football.
Rebuilding a squad in transition is rarely as simple as importing a cluster of familiar faces. While players like Seiwald, Veiga, or Solet know Jaissle’s style, few will arrive with an immediate grasp of the unique weight, culture, and expectations that come with representing Newcastle or a Premier League club.
Recruiting players who know the manager's playbook can certainly help with tactical implementation, but assembling a reshaped squad under a head coach who is still figuring out the club for himself is a delicate process.
Signing Jaissle's former players may well prove the evolutionary route Newcastle take in 2026/27 and beyond, but it is by no means a guaranteed blueprint for instant success.
