Archie Gray, the summer signing from Leeds United, played at full-back and also seemed to pick up a knock.
“He didn’t stop running though, so it can’t be that bad,” said Postecoglu, who also stressed the decision to replace in-form Brennan Johnson with Dejan Kulusevski was purely tactical and the son of former United Academy man David is “fine”.
Dominic Solanke, who scored against the Reds at Old Trafford for Bournemouth last term, also continued his good run with the third goal against Qarabag.
