Raphael Guerreiro looking forward to facing former club Borussia Dortmund in this weekend's Der Klassiker

Raphael Guerreiro is relishing the prospect of going head-to-head against former club Borussia Dortmund in this weekend's Der Klassiker.

It has certainly not been the easiest of seasons so far for Raphael Guerreiro, who swapped Borussia Dortmund for Bayern Munich last summer. The Portuguese international has struggled with a number of injury problems, and has been limited to just 21 appearances across all competitions as a result.

Guerreiro has recently been sidelined with a muscle fibre tear, but is hopeful of being fully fit in time for Saturday's Der Klassiker. This will be the 30 year old's first meeting against his former club, as he missed the reverse fixture due to a muscular injury.

And Guerreiro is excited about the prospect of going up against his former employers. In an interview with the Bundesliga, the left-back said, "It's a very important match for me personally as Dortmund was a big part of my life. I had some amazing moments there as well as some tough ones. Today, I'm very happy in Munich so I will give my all for Bayern."

"Everyone wants to watch Der Klassiker. When I was at Dortmund, we used to look forward to this fixture all year, and it was typically a bad experience for us whenever we played at the Allianz Arena. I hope we continue in the same way this time and Bayern get a good result."

Guerreiro also believes that Borussia Dortmund's direct playing style could cause Bayern a few problems this weekend, and has highlighted Donyell Malen as one of the players who could make an impact.

“Dortmund have had a few issues this term with their build-up play," Guerreiro said. "They have been looking to play direct rather than build through the phases. They are not always able to retain possession up front and then recycle the ball. I think things have improved slightly in their last few games though. I watch them a lot so I still have some ideas about how they play."

"Donyell Malen is in great form at the moment. Dortmund offer a real threat and have lots of explosive players. We were able to dominate in the first game against them this season. Now they are coming to Munich so we will show them what we are about here at Bayern."

Raphael Guerreiro joined Borussia Dortmund after making his breakthrough for Portugal at the 2016 Euros. He made a total of 224 appearances for the Black and Yellows, scoring 40 goals and assisting a further 50.
