Yup, Newcastle have no idea how to defend at the moment, that was beyond abysmal, just plainly embarrassing.
Pardew made a huge mistake with the subs, both Ameobi's are terrible, he took off a genuine chance to win the game, and whiel Obertan did well to set up a goal, he's done so little since he's been on in total. This is the game to leave both strikers on and go for it, get a second game with points and maybe even the win, mentally a huge push going forwards. I can understand wanting to rest them but this game was well in their grasp and resting them is daft.
If they were 3-0 down, take them off, but chance to win, keep them on.
