The winger believes Arsenal are a quality side and has backed an English team to reach the Champions League final this season.
The Gunners face the Germans on Tuesday evening desperately needing a positive result to keep their hopes of reaching the last 16 alive.
That is after they lost their first two European games against Dinamo Zagreb and Olympiacos to leave this European campaign hanging by a thread this season.
And Robben admits he was surprised that they lost those games as they are a strong side and can beat any team, insisting his side must be aware ahead of their crunch clash.
“I thought last season they did very well. They won prizes; the FA Cup and the Community Shield,” he told the Telegraph.
“They looked very stable and this year they look very strong. I was really surprised to see them lose two Champions League games but, on their good day, I think they can beat any team and we have to be aware.”
The Dutch star is also confident that the English sides will start to dominate European football once again at some point.
The Premier League is at risk of losing its fourth Champions League spot in future after a series of disappointing results and a failure to go far in the tournament in recent seasons has seen Serie A catch up in the UEFA Coefficients.
That came after a period in which English teams had dominated in Europe for several years as they regularly featured in finals and semi finals, and Robben says it would not surprise him if one were to make the final this season.
“You can discuss why English clubs have dipped in the Champions League for a long time but sometimes it is a small detail,” he added.
“These are the best teams in the world; one team has never won in consecutive years. It would not surprise me this year if an English team made the final. It can happen.”
