'Sky Sports' reported earlier in the week that Rooney was set to switch the 'Toffees' for MLS-outfit DC United for a sum of £12million.
However, one of his team-mates wants him to stay. Walcott told the English media outlet: "The legacy he has brought to the Premier League, the goals, the trophies, everything he has done at Manchester United, England and here, he is an incredible player.
"Obviously I'd love him to stay, I remember having a conversation with him on the phone, he was one of the main players who got me here, so I am grateful for that, definitely.
"But if he does choose to go on I just need to wish him all the best really, him and his family. He doesn't need to prove anything to anyone anymore.
"However, let's wait and see. Like I said, I'd love him to stay here."
