Newcastle boss Rafa Benitez admitted the Magpies only have themselves to blame after they dropped more points at Aston Villa.
Aaron Tshibola's late header earned the hosts a battling 1-1 draw after Tommy Elphick's first-half own goal almost gifted the Magpies victory on Saturday.
The visitors were on top for long spells and Dwight Gayle and Mo Diame wasted fine openings before Tshibola levelled with just three minutes left.
The draw left Newcastle fifth, four points behind Sky Bet Championship leaders Norwich ahead of the Canaries' visit to St James' Park on Wednesday, and Benitez knows they blew their chance.
