Inspired by a large decay branching ratio (BR) of B+→f0(980)K+ measured by Belle recently, we propose that significant evidence of the component of nn̄= (uū + dd̄)/ √2 in f0(980) could be demonstrated in exclusive b→c decays by the observation of f0(980) in the final states B̄→D0(*)π+π-(KK) and B̄ →J/ψπ+π-(KK). We predict the BRs of B̄→D0(*)(J/ψ)f0(980) to be (O(10-4) [O(10-5)] while the unknown wave functions of D(*)0 (J/ψ) are chosen to fit the observed decays of B̄→D(*)0π0 (J/ψK0(*)).
