The Manchester United striker and Toffees academy product risked incurring the wrath of his former fans by returning to Goodison Park for the clash with Villarreal.
However, the 29-year-old, who made a 25-minute cameo off the bench, received a warm reception, but did claim it to be an odd experience on the whole.
"It was a bit different today, going into the home dressing-room again," the boyhood Evertonian told the club's official website.
"It was a bit weird at first but, as I say, didn't know what to expect with the reception but it was a great reception."
Rooney left Everton for an estimated £30m back in 2004, and has since won 10 major trophies - including five Premier League titles - with the Red Devils.
