Alan Hansen on MOTD pointed out how the Newcastle midfield gave up the ghost against Spurs: "Watch this, as well as the two Spurs strikers, they have FOUR midfield players come into screen to support ... and not ONE Newcastle player tracked back.
"That is unthinkable!"
But Williamson claims there WAS heart in the team.
Mike Williamson: "Sometimes, the fans can be a little bit unfair, but you can't say that over the past few games. They are justified, and we completely understand their anger and upset.
"It might have come across to the fans that there was no heart, and that's a disappointing thing.
"Believe me, the players in there are feeling exactly the same.
"Now, it is all about getting that reaction and making sure we can convey our spirit and fight against Villa, when we've got to bounce back.
"What we have had at this club in years gone by is a reaction, and so when things like this do happen, the lads pull together on the training ground and go back to the basics of working hard and making sure we are compact and solid. Hopefully, that's where we are going to go.
"We've seen that side to him before. Every now and again, when it is necessary, he tears into us, but there needed to be some harsh words said because he felt it wasn't good enough from the players on the pitch.
"First, you do it for yourself, then the manager and the fans and the club. That's where it builds from but, yeah, we have let the manager down.
"We have let the fans down and we have let ourselves down, so it is all about getting back to the basics now."
