Clarifying EFL Cup semi-finals

It looks like the EFL Cup semi-finals are going to be one-off ties at the home ground of the first team drawn. I need to confirm this, but I believe that's correct since replays in the FA Cup were removed, not in the EFL Cup. The user provided pairs, but I can't tell which team is first drawn or deduce home/away. Maybe I should ask if they want details on dates or venues. I can also offer an analysis of each matchup.Providing match insights

I want to suggest predictions, but I should avoid giving betting advice. Basic probabilities seem okay, though. I can ask the user if they want pre-match analysis, predicted line-ups, or details about timing and team order. It’ll be helpful to keep things concise in bullet points and ensure compliance with formatting guidelines. I need to mention that since the 2024/25 season, the EFL Cup semi-finals are one-off matches, going straight to penalties if tied. I’ll look to clarify a few details on that!Summarizing EFL Cup rules

In recent EFL Cup rounds, matches that go to penalties after 90 minutes don't have extra time. I think that semi-finals used to have extra time if the aggregate is tied, leading to penalties in the second leg. But with single-leg semis, it seems they might go straight to penalties. I’ll word this cautiously. I should also mention match congestion and potential player rotation. I need to craft a concise response in Chinese, including quick analysis for both ties and a question to engage the user!
