The Premier League looks set to welcome another young head coach.Matthias Jaissle, 38, is set to take over at Newcastle United after Eddie Howe’s departure, as reported by The Athletic. That would make him the second-youngest manager or head coach in the English top flight behind Brighton & Hove Albion’s Fabian Hurzeler (33), and one of nine aged 45 or under.Jaissle will leave Saudi Pro League side Al Ahli, who, like Newcastle, are majority-owned by Saudi Arabia’s Public Investment Fund (PIF), after three years at the helm. The German has won trophies there but is better known in Europe for a successful two-season stint at Austria’s Red Bull Salzburg from 2021-23.The Athletic breaks down what we can expect from Jaissle once he is in situ at St James’ Park.Eddie Howe set to leave Newcastle United after five yearsDavid OrnsteinJaissle’s managerial career began in 2014 with assistant roles for German side RB Leipzig’s youth teams and at Denmark’s Brondby. That was followed by spells in charge of Salzburg’s under-18s and with sister club FC Liefering before he was named Salzburg’s first-team coach in 2021.He had an immediate impact. Salzburg won the Austrian Bundesliga that season, in which their Champions League campaign turned heads. Jaissle’s side beat his former team Brondby in the qualifiers before home wins against Sevilla, Lille and Wolfsburg helped them make the round of 16 for the first time. There, they held their own against Bayern Munich in the first leg, drawing 1-1, but were beaten 7-1 in the decider in Bavaria.Jaissle had laid down a tactical marker, though. Across that Champions League campaign, Salzburg ranked third among competing clubs for possession wins in the midfield third, with 28.5 per 90 minutes. They also ranked first for sequences of two or fewer passes at 104.3 per 90. Counter-pressing and direct play were at the heart of their success, and that has carried over following his move to Saudi Arabia.“I want stress on the opponent as soon as possible,” Jaissle said in conversation with The Athletic in January, two and a half years into his time with Jeddah-based Al Ahli, where he has won successive Asian Champions League titles in 2025 and 2026. “And when we win the ball, I want to go as quickly as possible towards the opponents’ goal. I’m very vertical in that approach.”Al Ahli often line up in a 4-2-3-1 or 4-3-1-2 shape, and their midfielders stay close to win back possession immediately after they lose the ball. We see this in their 2-0 loss to Al Nassr in April, after a turnover in possession creates the chance for a line-breaking pass.The pass is completed, but Al Ahli (white dots) instantly have two men moving to pressure the opponent in possession. He passes, but that triggers two more Al Ahli players to push up onto its intended receiver.Al Ahli instantly try to close down the player now in possession…… and when he passes to a team-mate, two more push up to do the same.Al Nassr manage to complete two more passes but a foul stops them going any further.Bold jumps from defence and work rate in midfield are keys to this approach — one that Newcastle executed brilliantly in their best stretches under Howe.
