Moyes is pleased the striker wants to stay beyond his current contract, and is looking forward to seeing more of his partnership with Wayne Rooney.
The manager said to journalists at a press conference on Friday afternoon: "I’ve been telling you that [he’s staying] but you’ve wanted to say or write something different.
"It’s difficult if you don’t believe what I say. Robin is happy here and I’m pleased about that. I didn’t know what was coming out – I’ve only just heard this morning about it.
"We’ll take it as it is. He has a couple of years to go on his contract and I’m sure that will be something the board look at.
"I’ve always said we’ve got two outstanding forwards in Wayne and Robin. Both have capabilities of winning games off their own back. They’re both pivotal international players and the sort of players any side in the world would want in their team.
