Concedes four

Ronnow had six saves and allowed four goals in Saturday's 4-0 loss to Bayer Leverkusen.

Analysis: Ronnow was frequently called into action as Leverkusen dominated in all thirds of the game. He made six saves and also managed 19 passes. Ronnow took the place of Matheo Raab and is also likely to face Schalke 04 next week.

Set to start Saturday

Ronnow (groin) is likely to return and is set for a starting role against Leverkusen on Saturday, according to Bullinews.

Analysis: Ronnow ended last season with an injury and finally seems to be set for a return after missing the opener this campaign, as the goalie is expected to start in net against Leverkusen. He was their regular starter last season, so this is a major return for the club, sending Matheo Raab to the bench. Ronnow should remain a starter if he is fit, recording five clean sheets in 30 appearances last campaign.

Ruled out Saturday

Ronnow (groin) is ruled out for Saturday's Bundesliga opener against Eintracht Frankfurt.

Analysis: Ronnow has been unable to earn a place in the matchday squad despite returning to collective training this week following the adductor issue that had disrupted his preseason, with coach Mauro Lustrinelli's cautious assessment proving accurate after the club decided the opener had come too soon. Union Berlin opted to give their starting goalkeeper the necessary time to regain his usual level rather than rushing him back, with Matheo Raab expected to start between the posts having already featured in the cup win over Eintracht Braunschweig. His availability for the coming fixtures will be monitored closely as he continues to build his fitness ahead of what is expected to be a demanding campaign.

Availability still uncertain for opener

Ronnow (groin) has an uncertain status for Union Berlin's Bundesliga opener against Eintracht Frankfurt, according to coach Mauro Lustrinelli. "His availability remains uncertain, we need to observe his progress. We know the situation can change from one day to the next, it's too early to say."

Analysis: Ronnow only rejoined collective training this week after his adductor issue, and the club wants to give its starting goalkeeper the necessary time to regain his usual level following the lengthy interruption. Matheo Raab and Carl Klaus remain the alternatives in goal, with Raab already having started the cup win over Eintracht Braunschweig, should the opener come too soon for Ronnow.

Returns to full team training

Ronnow (groin) returned to Union Berlin's team training Wednesday, marking an important step in his comeback, according to Welt.

Analysis: Ronnow suffered an adductor injury in late April during a defeat to RB Leipzig, causing him to miss large parts of preseason as well as the German Cup win over Eintracht Braunschweig. His return to team training puts him closer to a competitive appearance, though it remains unclear whether he'll be ready in time for Saturday's Bundesliga opener against Frankfurt, with his availability now dependent on how he holds up over the coming sessions. Matheo Raab and Carl Klaus remain the alternatives in goal should the opener come too soon, with Raab having started the cup match against Braunschweig.

Doubtful for league opener

Ronnow (groin) did not feature in Union Berlin's cup match and is now uncertain for Saturday's Bundesliga opener against Frankfurt, according to the club.

Analysis: Ronnow remains sidelined by a groin injury after missing the cup match and is uncertain for the league opener against Frankfurt. The goalkeeper has yet to return to full fitness, leaving his availability in doubt. Matheo Raab, who started in the cup, could get the nod again if Ronnow remains unavailable, though Carl Klaus could also be an option after finishing last season on a strong note.

Could miss cup opener

Ronnow (groin) remains well short of full fitness following his adductor injury and is unlikely to be available for the DFB-Pokal opener against Eintracht Braunschweig, according to Bild.

Analysis: Ronnow was unable to complete every training session during the club's camp in Styria, with his left arm bandaged at times. Backup Matheo Raab is also still dealing with training limitations following a serious hand injury suffered during his Bundesliga debut at Freiburg last season. As a result, Carl Klaus, the current third choice goalkeeper, appears best positioned to start the cup opener after finishing last season strong and impressing further during the summer camp, a performance that followed his contract extension earlier in the summer. Ronnow is expected to continue his recovery as the club's medical staff monitors his progress toward full training.

Jul 9, 2026

Yet to feature in preseason

Ronnow (groin) hasn't played in any of Union Berlin's first three preseason friendlies.

Analysis: The goalkeeper suffered a season-ending injury in late April, and his absence from friendly matches suggests he might not be ready to play yet. Union will play six more friendlies before opening their 2026/27 season against Braunschweig in the DFB-Pokal. Their Bundesliga campaign will begin against Frankfurt on Saturday, Aug. 29.

Season ending

Ronnow (groin) is out for the rest of the season due to a muscle injury in his groin, according to his club.

Analysis: Ronnow will not return for the final three games of the league season, as he will instead be held out as he recovers from a muscle injury. Unfortunately for the club, this will leave them without their starting keeper, leaving Carl Klauss to likely start, as Matheo Raab (hand) is also done for the season. Ronnow ends the campaign with a pretty average season, recording five clean sheets, 54 goals allowed and 77 saves in 30 appearances.

Adductor injury could end season

Ronnow suffered an adductor injury on the inside of his right thigh during Friday's loss at Leipzig and could miss the remaining three Bundesliga fixtures if the diagnosis is confirmed, according to BILD.

Analysis: Ronnow had to be replaced in the 31st minute after taking a knock and being unable to continue, and the reported diagnosis points toward an absence of several weeks that would effectively end his season. An official confirmation from the club is still pending, but the situation is deeply concerning for Union Berlin given that second-choice goalkeeper Matheo Raab (hand) is also sidelined for the rest of the campaign, leaving Carl Klaus as the most likely option to step between the posts for the final stretch of the campaign.

Apr 24, 2026

Subs off against Leipzig

Ronnow suffered an injury after taking a goal kick in the first half of Friday's visit to Leipzig.

Analysis: Ronnow made two saves and conceded two goals over half an hour of play before his forced withdrawal. While his injury still needs to be assessed, he's at serious risk of missing future action, which would leave the team without its first and second-choice keepers given that Matheo Raab (hand) is also sidelined. Therefore, Carl Klaus could get some rare opportunities after replacing Ronnow in the weekend's game.
