You don't think Grealish was playing to instructions then?I don't agree with this.
I think Grealish went from a team where he was THE only creative source so one with an abundance of creativity, so he's chosen the safety first option. This has clearly vexed Pep, who went out and bought Doku to do the job Grealish was brought in for. Ergo Doku displaces Grealish in the starting line-up.
I don't see anyone saying Pep has ruined Doku.
