Olimpija Ljubljana’s young captain Marcel Ratnik is increasingly outgrowing the Slovenian top flight. The 21-year-old defender is already the leader of the back line and offers standout quality on the ball – with his modern profile, statistical production, and international experience, he’s ready for the next step in his career.

Wearing the armband at a young age is always meaningful – especially at a club that holds a central role in its country’s footballing identity. Olimpija Ljubljana, the capital city’s premier club, is one of the best-known sides in Slovenia, and Marcel Ratnik’s status as captain before his 21st birthday speaks volumes about both his personality and his performances.

The centre-back from Murska Sobota began his footballing journey at his hometown club, had a brief spell with Maribor, and finally joined Olimpija in 2017, where he has steadily progressed through the ranks. He’s featured prominently for every Slovenian youth national team and is now a regular name in the senior squad’s extended roster.

Ratnik stands 186 cm tall, is right-footed, and primarily operates in central defence, though he is also capable of filling in as a right-back when needed – his physical profile helps with that versatility. With long limbs and an ectomorphic build, he’s not particularly muscular, but highly agile and well-conditioned. Over the last two seasons, he’s consistently handled the demands of a two-match-per-week schedule – not just physically, but mentally as well. And it’s that mental aspect that may be the most important factor in his development going forward.

“I’m very happy in Ljubljana right now, but I won’t hide my ambition to try myself abroad. I believe I’ve shown a lot in Slovenia, and in my opinion, I’m ready for the next step. My biggest dream is to sign for a club abroad – not just for football, but to ensure financial security after my career. So that by 35 I can enjoy life knowing I’ve already achieved everything I wanted.”

DEFENSIVE PROFILE

Since the appointment of Víctor Sánchez last summer, Olimpija Ljubljana has adopted a possession-dominant style. They lead the league in both possession percentage and Field Tilt – the latter indicating that the majority of their play takes place in the opponent’s half. This naturally means a high defensive line, which places a premium on centre-backs who can control space and intervene proactively. In Ratnik’s case, these are clear strengths.

• Defensive intensity - 40th percentile
• Ball recoveries - 37th percentile
• Interceptions before tackle - 66th percentile
• Tackles - 49th percentile
• Tackle success rate - 63rd percentile

The data shows he’s not the league’s most active defender statistically, but he consistently picks the right moments to engage and is highly effective in anticipatory duels – choosing to read and prevent actions before they become direct contests. This is crucial, as while his top-end speed is not elite, his acceleration and changes of direction are excellent, allowing him to recover behind a high line when needed.

Despite his age, Ratnik already acts as the defensive organiser on the pitch. He communicates constantly, positions his body well, and reads the game with maturity. He knows how to force attackers onto their weaker foot or into tighter passing lanes. Notably, he handles most defensive situations cleanly – avoiding unnecessary fouls and bookings – which is a strong indicator of both discipline and defensive intelligence.

During defensive transitions, he often acts as the deepest line of cover, meaning his first movements are usually forward. There is still room to grow here: his pressing angles, scanning frequency, and awareness when the opposition breaks lines need refinement – he can be late to spot runners or dangerous passing lanes.

ON THE BALL

Ratnik is a vital cog in Olimpija’s build-up phase. As a right-footed centre-back, he fits the profile of a ball-playing defender – and his passing stats back that up. He ranks among the league’s best in progressive passing, both in volume and accuracy. Whether in short buildup or longer diagonal switches, he consistently breaks lines – especially against mid- or low-block sides that don’t press aggressively.

• Total passes 74th percentile
• Pass accuracy 94th percentile
• Progressive passes 71st percentile
• Progressive passes accuracy 74th percentile
• Passes into final third 63rd percentile
• Final third pass accuracy – 86th percentile
• Forward pass accuracy 80th percentile

These numbers suggest not only that Ratnik looks to pass forward frequently – but that he executes those passes at a high level. He’s one of the team’s key outlets for vertical progression from the back. And when there’s no obvious pass, he’s not afraid to carry the ball into space himself – often bypassing multiple opponents or zones through direct dribbling.

• Carries - 63rd percentile
• Carry distance - 86th percentile
• Progressive carries – 80th percentile

Ratnik’s creativity from the back is also borne out by his chance-creation stats. These kinds of numbers are rare for a centre-back – usually seen only in wide centre-backs within back-three systems. But Ratnik manages to produce these metrics even while playing in a back four, which further highlights his technical and tactical value in possession.

• Passes into the box - 71st percentile
• Key passes - 91st percentile
• Shot-creating actions - 80th percentile
• Through balls – 80th percentile
• Big chances created - 74th percentile
• Expected assists – 77th percentile

This hidden playmaking ability is a result of Ratnik’s sharp understanding of the game – he’s not afraid to target tight central zones, either with driven passes to feet or lofted balls into space. He also shows good decision-making in terms of when to attempt riskier passes, and he rarely gives the ball away in the attacking third.

Though he didn’t score a goal this season, Ratnik still plays a vital role in set-piece situations. He often appears in dangerous areas around the box, but he’s not always the intended target – Olimpija often uses him as a decoy to drag markers away from the primary target zones. This off-ball contribution (gravity) is part of why the team ranks amongst the league’s best in goals from dead-ball situations. Last season, he scored three headers, and his current goalless run seems more a reflection of tactical function than form.

CONCLUSION

Marcel Ratnik’s game already features many of the traits required at higher levels: smart positioning, vertical passing, and proactive defensive interventions. While he still needs to improve against more intense pressing systems and in controlling central transitions defensively, his basic technical skills and decision-making offer a strong base for development.

His performances in a UEFA competition have further shown he can hold his own beyond Slovenia. If he continues on his current development path, a move to a top-five league this summer would not be a surprise – whether as an immediate rotation option or part of a longer-term project.
