Celtic Football Club have announced the arrival of German midfielder Mika Baur, sealing what is now their fourth signing of the summer window. The 22‑year‑old joins the Scottish champions on an initial four‑year contract that includes an option for an additional year, signalling the club’s long‑term belief in his abilities.
The transfer fee is reported to be in the region of £6.8 million overall. According to Sky Sports News, the upfront payment is expected to be roughly £4.5 million, with a further £2.3 million in performance‑related add‑ons.
Those bonuses are structured similarly to the agreements Celtic reached with other recent acquisitions such as Camilo Duran, Kasper Høgh and Haissem Hassan – a sizable portion will be triggered if Celtic progress to the group stage of the UEFA Champions League. Baur arrives from German side SC Paderborn, a club he helped elevate from the 2. Bundesliga to the top flight of German football last season.
During that campaign he featured in 33 league matches, contributing four goals and five assists, performances that earned him the honour of Paderborn’s Player of the Year. Prior to his stint at Paderborn, Baur developed through the youth system at SC Freiburg, making his move to Paderborn in 2024 after impressing at various youth levels. The midfielder’s signing comes at a crucial juncture for Celtic, who are preparing for a Champions League play‑off tie against Austrian side LASK Linz next week. Should the club secure a place in the group stage, Baur could be registered as part of the squad for the European competition, adding depth and versatility to the midfield roster.
Speaking about his decision to move to Scotland, Baur expressed enthusiasm for the challenge: "It’s absolutely the right move. It’s a great club and I’ve heard incredible things about the fans.
I’m in the same agency as Nicolas Kuhn, so I called him to ask a couple of questions and he was so positive. He said, if you have the chance, just do it. I’ve had a good pre‑season with good matches and tough training sessions, everything. So I’m in good shape and I’m ready to go." His comments underline both his physical readiness and his mental eagerness to integrate into Celtic’s setup.
Celtic’s manager, Martin O’Neill, welcomed the addition, highlighting Baur’s technical qualities and tactical flexibility: "I am delighted that we have been able to bring Mika to Celtic. He is a player with some excellent attributes, great technical ability, he will be important in linking our play and he has real versatility too. Having spoken to Mika, I can see the appetite he has for the challenges here at Celtic and I am sure he will be another great addition to the squad.
Mika’s club in Germany were very keen to keep him, which I fully understand, as he played such an important role in their Bundesliga promotion, but I am really pleased with the perseverance and commitment we have shown to secure his signing." The strategic nature of the deal reflects Celtic’s broader ambition to strengthen the squad ahead of a demanding season that includes domestic league fixtures, cup competitions, and the prospect of European football. By securing a midfielder who has already demonstrated the ability to perform under pressure and contribute both goals and assists, Celtic aim to enhance their creative options in the centre of the park. Baur’s experience in a promotion‑winning side also brings a winning mentality that could prove valuable in high‑stakes matches. Beyond the on‑field implications, the signing is also a statement of intent in the transfer market.
Celtic have shown they are willing to invest significant resources to attract young talent from abroad, competing with clubs from larger leagues for promising players. The inclusion of performance‑based add‑ons tied to Champions League qualification further illustrates a pragmatic approach: the club mitigates financial risk while rewarding the player and his former club for success. Fans of Celtic have already begun to discuss Baur’s potential impact on the team’s style of play. Many anticipate that his ability to link defense and attack will complement the existing midfield unit, providing more fluid transitions and increasing the variety of attacking patterns.
His versatility means he could be deployed in several roles – as a deep‑lying playmaker, a box‑to‑box presence, or even in a more advanced position when the tactical situation demands it. In summary, Mika Baur’s move to Celtic represents a carefully negotiated acquisition that balances immediate squad needs with future planning. The four‑year contract, with an optional fifth year, gives the club a stable platform to develop the player further, while the structured fee and add‑on system align incentives for both parties.
As Celtic prepare for their upcoming Champions League play‑off and the start of the Scottish Premiership, Baur’s arrival adds a fresh dimension to a team eager to compete on multiple fronts and to continue its tradition of success both at home and in Europe.
