Manchester United boss David Moyes felt they produced a complete performance for their 3-0 win at West Bromwich Albion.
Phil Jones, Danny Welbeck and Wayne Rooney struck the goals for United.
"All areas pleased me today," Moyes said.
"There were some very good performances. Marouane Fellaini did really well, Phil Jones and Chris Smalling were excellent. I thought the two boys up front were fabulous, with Juan (Mata) and Adnan (Januzaj).
"I saw by their attitude had changed completely (from the Olympiacos game).
"They showed their effort and commitment, not just good play."
