Ex-Everton striker Wayne Rooney was given a standing ovation by the club's fans when he came on as a substitute for the Blues in Duncan Ferguson's testimonial at Goodison Park.
Rooney, 29, made 77 appearances for Everton before joining Manchester United for £25m in 2004.
In front of 34,718 fans, he came on for the last 15 minutes against Villarreal.
"I didn't know what to expect with the reception, but the fans were great," Rooney told Everton TV.
"I really appreciated it. More importantly it was a big day for Duncan. I said to him before the game that it was the most nervous I had seen him."
The Spaniards won 2-1, ex-Blues striker Ferguson coming on in the 83rd minute.
Rooney has frequently received a hostile reception from Everton fans when he has returned to Goodison Park with United.
He is expected to start United's first game of the 2015-16 Premier League season against Tottenham Hotspur at Old Trafford on 8 August.
