Let's talk about the positives here:
1) Has become more aggressive in defense. Tackles more, runs more, tracks back more and etc. Huge improvement compared to the first part of the season.
2) Each time he gets the ball near opponent's box - you always expect something incredible to happen. That pass to KDB when he hit the bar and Jack's movement in small space / between the lines before that pass - reminded me of David Silva.
3) Never looses the ball and never risks too much - more of a team player. For example Cancelo risks a lot and tries to impact the game more, Jack is calmer and tries to support guys.
Definitely he is improving and getting better day-by-day. I'm sure he will be one of our KEY players soon, just give him some time to settle more and grow a reputation among teammates, rest will come, talent and end-product is there..
Why do the forwards we get always need a year or more to settle?
I know its not his fault for the price but for £100m I would have hoped he wouldn't need a year to do anything of note.
I'm sure he will come good but for me a really bizarre signing.
