However, with the Foals currently in the midst of a three-game losing streak, emotions will play not part for the 29-year-old, who continues to thrive under the tutelage of Lucien Favre, a head coach who has had a significant influence on his professional career.
Speaking exclusively to bundesliga.com ahead of the visit of Hertha Berlin on Saturday, the Fortaleza native sheds light on his relationship with brother Ronny, Gladbach's current dip in form and the breathtaking battle currently taking place for a top-four spot in Germany's top flight.
bundesliga.com: Raffael, you’re up against Hertha and your brother Ronny on Saturday. Have you had any bets with him on the result?
Raffael: (laughs) Not yet, but I’m sure we will [before Saturday].
bundesliga.com: Is the game against Hertha particularly special for you?
Raffael: Yes, definitely. I’m playing against Hertha, my old club, and against my brother. It’s going to be a real highlight for me.
bundesliga.com: Have you been in touch with Ronny in the build-up to the game? Are you still in close contact?
Raffael: Yes, we always talk before games and we’ll definitely be in touch before the weekend. Of course we don’t talk quite as much as we did when we were both at Hertha, which is a shame.
bundesliga.com: Do you dream of one day playing on the same side as him again?
Raffael: I do, yes. Maybe it’ll happen sometime in the future. We always played together as kids on Fortaleza, on the street and with our clubs. Even when I was a youth player at Juventus Sao Paulo we were always together. Of course, nobody was expecting both of us to end up in the Bundesliga.
'Ronny's an almost complete player in my eyes'bundesliga.com: And who won when you played against each other?
Raffael: (laughs) Sometimes Ronny, sometimes me. They were always good match-ups.
bundesliga.com: Who’s the better player nowadays?
Raffael: I always say Ronny. He’s an almost complete player player in my eyes. He has so many qualities.
bundesliga.com: And he probably says that you’re the better player…
Raffael: (laughs) Yes, that’s probably the case.
bundesliga.com: What memories do you have from your time at Hertha? The fans thought very highly of you for staying at the club after their relegation to Bundesliga 2 in 2010.
Raffael: I have many memories of my time at the club. I was there for four years and we went through a lot together. Our promotion and the two relegations stick in your mind in particular. I have a big connection with the club and continue to follow them closely.
bundesliga.com: After brief spells at FC Dynamo Kyiv and FC Schalke 04, Mönchengladbach seems to have become your second home.
Raffael: Yes, I’m very, very happy here. I have been since the day I arrived. The people are all friendly, we have great fans and Gladbach is a good city. Everything’s great here.
'There's never a dull moment with Favre'bundesliga.com: Can you see yourself staying at Gladbach for a long time to come?
Raffael: Yes, that’s the plan. There’s no reason to change clubs.
bundesliga.com: Did Lucien Favre play a big part in your decision to move to Gladbach in 2013? You’ve played for three different clubs under his tutelage.
Raffael: Absolutely, he convinced me really quickly. He’s played a very important role in my career and took me to FC Zürich from the Swiss second division in 2005. He’s a special coach in my eyes, a special person who’s very important to me. Who knows what path my career would have taken without his influence?
bundesliga.com: Is he the best coach you’ve worked under?
Raffael: Definitely. Everything he sets out to do he does so well. Whether it’s in a match or in training, working for him is a lot of fun every day. There’s never a dull moment with him.
bundesliga.com: His record has been excellent too. Gladbach have improved year upon year since his arrival in February 2011. Are the team better than they were last season?
Raffael: I think so, we’re incredibly strong this season. We’re playing better football, which is in no small part down to our new players. They’ve all impressed me, especially Ibrahima Traore and Thorgan Hazard.
'It’s fun to play with Traore and Hazard'bundesliga.com: Both those players have often had to settle for a place on the bench though. Have they got enough about them to merit a place in the starting eleven?
Raffael: Most definitely. Both are intelligent people, they play a simple game and it’s really fun to play with them.
bundesliga.com After going on an eighteen game unbeaten run in all competitions, Gladbach have now lost three consecutive games in the Bundesliga. What’s gone wrong?
Raffael: We were a bit unlucky in those games, which is very annoying. We have to keep going, keep working hard, then we’ll start scoring more goals. The goals will come, for me personally as well. I’ve had two or three chances in every game, but I’m bound to find the net again eventually.
bundesliga.com: Could the lack of goals be down to Gladbach’s system? You play without an out-and-out striker, and you and Max Kruse often come deep.
Raffael: I don’t think so. We played that way last season as well and everything worked fine then. I enjoy the flexibility of our system.
'We have to beat Hertha'
bundesliga.com: Could the result against Hertha be an indicator of where Gladbach will finish this season? You’re now three points off third place, but only two above ninth.
Raffael: The game is very important, but the same can be said for every match. We desperately have to beat Hertha on Saturday. The teams behind us have caught up with us in recent weeks.
bundesliga.com: Borussia are currently fifth in the league. Can you qualify for the Champions League?
Raffael: It’s too early to say. The season is too long and so many things can happen. We just have to focus on ourselves and try and pick up points every game, then we’ll have a chance.
bundesliga.com: Who do you regard as your main rivals in the battle for a top-four place?
Raffael: Bayern already have a big advantage, but I don’t think you can rule out anyone this season. Only ten points separate fourth and 18th place, even Dortmund still have a chance of qualifying for the Champions League.
bundesliga.com: After playing Hertha you’ve got another treat in store: a game against your former club Zürich in the Europa League.
Raffael: Yes, I’ve got many fond memories. My time in Zürich was very successful, I won the league twice in my two years there and I still have many good friends in Switzerland.
bundesliga.com: A draw against Zürich would be enough to seal your place in the knockout rounds of the Europa League.
Raffael: We have a great chance to reach the second round and we’re playing at home. After that, anything is possible, but we have to take one game at a time. There’s a long way to go until the final.
