• Hoffenheim host Hertha on Sunday.
  • Nagelsmann's side still unbeaten after eight matches
  • Süle keen to underline impressive run of form.

It will take more than a narrow DFB Cup defeat at the hands of 1. FC Köln to dampen the mood in the TSG 1899 Hoffenheim camp, according to influential defender Niklas Süle.

The Sinsheim club are unbeaten in the Bundesliga this season, and that is how the Germany international would like things to stay after the Matchday 9 clash with fellow surprise package Hertha Berlin on Sunday afternoon (kick-off: 15:30CET/14:30GMT)...

Watch: Highlights of Hoffenheim's crushing 3-0 win over Leverkusen: Niklas Süle, the extra-time loss to 1. FC Köln in the second round of the DFB Cup was Hoffenheim's first competitive defeat of the season. What went wrong in the end?

Niklas Süle: Until the equaliser, we dominated the game and hardly gave Köln a chance to get into the game. We were doing a good job, but then [Marcel] Risse equalised with a stunning strike. We still had chances after going 2-1 down in extra time. Unfortunately we couldn't convert them. It's annoying to go out of the cup in this way.

Süle: No, we didn't lose in normal time, so technically we're still unbeaten (laughs). A lot can happen in the DFB Cup. We played a really good away game. Unfortunately it wasn't enough, even though we dominated in all areas according to the statistics: more shots on goal, more possession, more tackles won. We did well to post numbers like that away from home, against that kind of backdrop, but we didn't get the goals and that's why we went out. It's back to the Bundesliga with a home game against Hertha Berlin on Sunday. After that, you travel to FC Bayern München. How will you approach the Hertha game?

Süle: It'll be another difficult game. Hertha beat Köln last time out and will want to consolidate their position towards the top of the table, but we have the same objective. It'll be a great game. We have to play like we did in the DFB Cup defeat to Köln, but take our chances.

"We want to maintain the upward trend we've shown in recent months." Hoffenheim are unbeaten in the Bundesliga this season after eight matches. What makes the team so strong?

Süle: We have a game plan for each opponent that we're able to implement well. Last week, for example, we reacted well to Bayer 04 Leverkusen's system. We couldn't have been more deserving of the win. We want to build on that performance in the coming games.

Kevin Vogt has also shored things up defensively. How have you managed to integrate such different types of players so quickly?

Süle: We've brought in some really good players and also kept hold of the core of the side from last season. It's all going very well. The newcomers have integrated brilliantly. Our coach Julian Nagelsmann always has a plan. We don't just have one system; we're able to adjust according to every team we come up against. You can see that in every game. We're playing better with the ball now because we're able to enjoy calmer spells of possession. That's important because we're always going for it and we press a lot.

Süle: We musn't get too hung up on the start we've made. We want to maintain the upward trend we've shown in recent months and perform on the pitch - then we can have a good and trouble-free season. That's what we want.
