Is the defence a problem because of the GK? I think a solid GK like Pope behind them, for instance, gives the back 4 a lot of confidence.
I think we will not know if our defenders can cope until you give them a goalkeeper they have confidence in and a midfield that can screen them and hold the ball to give them a break. I would hate to be in our back four, you are concerned about the keeper behind you and you can’t relax when our midfielders have the ball because they will give it away and you are back under pressure.
