Everton football chief Marcel Brands says any new signing must have a good relationship with the support.
Brands told evertontv: "Players have to feel at home here and that's so important.
"I had the feeling he [Gomes] was a big example as are other players like Mina, Digne who also immediately at the beginning feel at home.
"It helps me a lot if the fans show that kind of appreciation to player. At the end, of course money is one thing, but you also want to be appreciated.
"I think that helps a lot. I think the fans are happy, but I'm also happy that they support me and this deal."
