Despite the club crashing out of Europe's premier club competition in the group stage in the past two seasons, Kompany believes it is 'inevitable' they will hold the cup aloft in the near future.
"We will win the Champions League one day. It is inevitable," Kompany told RMC. "The same question arose concerning the Premier League and we did it.
"With the investment being made in all areas of the club, that will surely come. When we see people like [Patrick] Vieira it's one of the things that can help us move forward. In Europe, we will be more competitive."
