Middlesbrough's Carabao Cup campaign ended with a 3-0 defeat at Premier League Crystal Palace on Tuesday, a result that cast a harsh light on striker David Strelec's ongoing struggles. The Slovakian forward, a £6m signing from Slovan Bratislava 12 months ago, started his first game of the season but failed to impose himself as Boro exited the competition.

Despite the scoreline, Middlesbrough battled well and were arguably the better side in the first half at Selhurst Park. Manager Hellberg made eight changes, handing debuts and opportunities across the pitch. Sol Brynn, who started all three cup games this term, made two excellent saves before Palace found their breakthrough. Callum Brittain and Aidan Morris proved their capability at the top level, while Adilson Malanda competed well in an unfamiliar midfield role and teenage winger Amario Cozier-Duberry was particularly impressive on his debut.

What does David Strelec's performance mean?

David Strelec's first start of the season was a major talking point. The 25-year-old, who had managed just nine minutes across two substitute appearances prior to this match, looked unsuited to the high-intensity pressing Hellberg demands. He struggled to impact the game and has looked an easy night's work for most defenders he has faced. This comes after Boro invested heavily in attack this summer, spending £8m on a new striker with the potential for that fee to rise to £20m. With the Greek transfer window open until September 15, Strelec has been linked with a move to PAOK. His ability is not in question, shown by goals for Boro and his country, but it currently feels off for him to be a good fit for this team.

How important is Will Lankshear to Middlesbrough?

The contrast with Will Lankshear's form is stark. The young striker has already netted seven goals this season and is a constant nuisance for defenders. His absence through injury would be a significant blow, especially as other attacking options Tommy Conway and Kyle Joseph are often preferred in wide areas and have been noted for lacking a natural goalscoring instinct. Boro's promotion hopes, with the team sitting 3rd in the Championship on 10 points from five games, may hinge on keeping Lankshear fit. They are just one point behind leaders West Ham and have scored eight goals while conceding five so far this campaign. You can track the team's progress in the standings.

What did Hellberg say after the match?

The Boro boss was philosophical about the defeat and the performance of his rotated side. "I could never believe in going anywhere and just trying to play off the opponents mistakes," Hellberg said. "We came here, switched a lot of players, and tried to play our best way of playing football." He also addressed the challenge of integrating squad players, noting, "It’s that balance for giving them the opportunity to be good when they start a game." The international break will now be used as a mini pre-season to rebuild fitness and integrate new signings before the Championship resumes.

What's next for Middlesbrough?

Attention immediately turns back to the league promotion push. Middlesbrough's next fixture is a important home game against Norwich City on September 12. The team will aim to maintain their strong early-season form, which reads WDWLW from their opening five matches. They will have to do so without the sidelined Jeremy Sarmiento, whose absence is noted on the club's injuries page. The extended break before the next Carabao Cup round allows full focus on securing another three points at the Riverside, a vital step in their quest for automatic promotion.
