The defence is concerning but let's not forget that Morgan had to concentrate on his partner more than normal which ended up taking it's toll on his own performance.
Clearly he prefers to play on the right side of the pair, moving him unsettles not only both central players but both wing backs who are dealing with different players to normal.
The above doesn't excuse all the missed headers though. He was beaten time and time again in the air and it directly led to one goal and should have led to another.
Drinkwater had no outlet and looked increasingly frustrated with the fact that nobody wanted to actually move to take the ball off him. He had to resort to punts up field whoch they gobbled up every time. Okazaki would have been coming short and dragging at least one defender with him in these scenarios which naturally opens up a bit more space in behind.
King being closer to the starting line-up than ever before suggests our activity in the market has been poor. He is not a starter and doesn't have any specialist traits that make him stand out.
Gray cannot start against the Arse, Albrighton needs to be back in and worked to death up and down that left hand side and replaced when needed.
Vardy needs to sharpen up, nothing more at this stage.
Kasper needs a massive kick up the arse, poor at every single cross and his abysmal distribution constantly out us under pressure, it eventually cost us the game.
