Let λi (i=1,...,k) be any nonzero complex scalars and φi (i=1,..,k) be any analytic self-maps of the unit disk \mathbbD. We show that the operator ∑i=1kλiCφi is compact on the Bloch space B if and only if limn→∞‖λ1φ1n+λ2φ2n+...+λkφkn‖B=0. We also study the linear combination of composition operators on the Banach algebra of bounded analytic functions.
