Koeman not only believes that Rooney fits perfectly into his plans at Everton, but he also thinks he is far from the faded force that many felt he was becoming at United.
Wayne Rooney had an instant impact on his return to Goodison Park, scoring the winning goal in a 1-0 victory over Stoke City earlier this afternoon.
"We've got some tough fixtures coming up and it was important we got off to a good start and that will give us all confidence going into the next game".
Rooney's header, which he placed beyond Jack Butland moments before half time, was the first effort of any note during the opening 45 minutes. Involved in Everton's impressive build-up play, he continued into the box and nodded home Dominic Calvert-Lewin's fine cross.
"Saturday will be a hard game".
"He was clever, he was comfortable on the ball".

Between that June day and his death on August 8, 2017, Campbell managed to release four albums, including Adios this year. Campbell was an anomaly, a musician whose technical and emotional approach never felt compromised or false.
"We need to find other ways and we need to find productivity from other players".
Koeman knows Everton can do "much better" and expects his new-look side to become a more cohesive unit as the season progresses, pointing to the string of big-name players out through injury.
"We still have three players out on long-term injuries in Seamus Coleman, Yannick Bolasie and Ramiro Funes Mori, but they are doing well", Koeman told the club's official website.
For me personally, to win a trophy at the club I've grown up supporting would be great.
