Jack himself has recently said he wants to play in an 8 role, he doesn’t want to be limited to the LW. He’s spot on, he would excellent playing more centrally. He’s not an out and out byline winger and never has been.
What shouldn’t happen is what Pep has been persisting with this season: Grealish OR Doku. It’s a big mistake for me, he should be finding ways to get them on the pitch together. Doku has struggled to date against bigger sides where more defensive work is needed (see Spurs, Chelsea, Arsenal) and I still wouldn’t have him anywhere near major games. Doku was also originally bought to play on the RW and bizarrely Pep is averse to playing him there. When Pep takes Grealish off for Doku we lose all of Jack’s attributes in ball retention, work rate and tracking back that are much needed. Fine against Huddersfield but would be mad in a bigger game. Not saying Doku can’t do that in time but he’s a million miles away at the moment.
Jack’s rhythm was broken by the burglary recently, he’d been getting better and better with consistent 90 min runs before that and chipping in with goals. If Pep has any sense he will start incorporating Doku into the RW position rather than wasting Jack’s ability by consistently hooking him at 55 mins after tackling low blocks (read, poorer teams) so Doku can breeze in against tiring opposition. Doesn’t do Jack any favours and also won’t do Doku any favours with regards to his development.
