I think after that performance, I think, people may be turning around on him.
Just to add a bit in terms of his style and what the stats show here are some PER 90 stats from FBREF:
xG: 0.24 with him scoring only 0.18, Kevin has 0.26 but scoring 0.42 (he has having a freak scoring season). Grealish ranks quite low on this list for our forwards in terms of getting in chances, but also in terms of finishing them off.
This is imo the biggest part of his game to work on, the rest you will see, is VERY strong and important to how we play and why I think he is vital for our big games this season over Sterling and Jesus.
xA: 0.27 - 3rd best in our team behind KdB and Foden. Mahrez and Gundogan are right around there also.
BUT I want to focus on 2 stats that I think if it existed during David Silva's time here he would have gotten more accolades from people who focus only on goals and assists:
SCA: Shot Creating Actions records the 2 actions taken before a shot is had (pass, dribble or drawing fouls), Grealish has about 5.5 SCA, highest in the team with KdB just behind with 5.4, 3rd best is Mahrez with 4.1.
Basically, he keeps the attack ticking, doesn't risk too much, but usually his actions lead to a shot more often than not, this is SO vital to a Pep team. It is not a sexy stat like Key Passes or xA, but I think should be in more conversations to define forward players who are more team players in a sense.
Progressive Carries into the 18 yard box (CPA): There are many stats about progressive carries, many leaning towards defenders who obviously have lots of space to run into, this is the best stat for forward players to see how well they progressive into the box.
Grealish makes 4.4 progressive carries into the box every 90 minutes. The 2nd best? Mahrez with 2.34 and Sterling just behind that with 2.3. Grealish ranks obscenely high in this regard, and again, not a sexy stat, but another stat I feel is super important for a pep forward.
