Bit harsh, if you're trying to play a possession based system with 3 at the back, all your CB's need to be good with the ball and Walker is our best option, that's why he was used. Look at the alternatives and it is basically Cahill....or Jones... who are both awful with the ball.
All about Lingard and Alli's movement between the lines and off the ball generally, it was superb first half, second half big drop off. Not using it as an excuse but apparently the heat in that place was hotter than anywhere that has been played in WC thus far.
I wouldn't change much at all, other than Loftus-Cheek perhaps filling in alongside Hendo. As soon as you start sacrificing attacking players and introducing Dier you're getting conservative again.
Ok it's only Tunisia, but apart from penalty they didn't create anything really.
