We are completely devoid of any pace and directness when both Mahrez and Grealish play.
Opponents know neither will go down the outside because they need to chop the ball back or inside, to afford themselves that yard of space to then work in.
Ironically, our goal came yesterday because Mahrez changed the habit of a lifetime by fooling his marker and going on outside.
Sadly, like with all signings we make, we are desperate for things to work out, but I fear Jack is already proving a costly mistake.
He doesn't have the ball skills of Mahrez to beat his man and so he does look clumsy and invariably draws the foul because the first touch out of his feet isn't quick enough.
His reaction to Haaland's first goal at Leeds showed how much it meant to him, even though it was an act of unselfishness which hardly pushed the footballing boundaries, with Pep even suggesting when his head is more confident, he might take those opportunities on himself?
Jack seems a good lad and the manager and players are clearly pulling for him to come good, yet unlike other players we have, he doesn't have the versatility to thrive in other positions.
The £100m fee isn't his fault, but it is the first time I felt we have made a United-type statement signing since Bony, where the public hype train was greater than the talent on display.
Similarly, how the cult of personality created a national group think that Sterling was still operating at an elite level in his final 18 months with City.
Jack wasn't a kid when he joined us, he's had more than a year to show there is more to come, and it still isn't.
Phil is a better fit for the team on the left and even Cancelo and Palmer have shown more threat in those areas of the pitch.
We need Jack to be chipping in with eight or ten goals a season and his record doesn't suggest he has ever been that?
My ideal three would be Foden, Haaland and Alvarez, from an intensity/goal threat perspective and hopefully we get to see more of that in the coming months and in Europe.
Jack isn't going anywhere soon and earns more than most. There comes a point, however, where in the next few weeks he needs to make the ultimate step, or we need to accept City and Pep got this one wrong.
Just as Chelsea did with Lukaku. A good player, yes, but in the wrong team and environment.
I'd have loved City to have been scouting someone like Luis Diaz at £37m :(
It's why, as much as I have loved Bellingham and his energy, I even question if I'm right, in terms of his City fit?
