Chelsea should have added another in the second half, with David Luiz hitting the crossbar with a free-kick, but the tie remains finely-poised for next Thursday’s second leg at Stamford Bridge.
Frankfurt were the better side in the opening exchanges and captain David Abraham could have put the hosts ahead in the 21st minute after Fliip Kostic’s free kick was flicked on into his path, but he lifted his shot over the crossbar.
