Neither Chelsea nor Liverpool could find a breakthrough in regular time as the FA Cup final went to extra-time at Wembley.
Christian Pulisic had a number of chances to open the scoring for the Blues while Luis Diaz was electric in the Liverpool attack and went close on numerous occasions.
But it was Andy Robertson who should have found the late winner, clattering the post with a volley at the back post after a fine cross from James Milner.
There were injury concerns for Jurgen Klopp throughout regular time with Mohamed Salah taken off with a groin issue in the first half and Virgil van Dijk substituted after the 90 minutes were drawn to a close.
