CR7 is a luminous Ly$\\alpha$ emitting galaxy at $z=6.6$ that consists of three separated UV-continuum components. Our observations reveal several well-separated components of [CII] emission. The two most luminous components in [CII] coincide with the brightest UV components (A and B), blue-shifted by $\\approx 150$ km s$^{-1}$ with respect to the peak of Ly$\\alpha$ emission.
