The England icon is set to enter the final year of his contract at the end of the season, which would leave him just 12 months away from being able to leave Old Trafford on a free transfer.
United are said to be keen to open negotiations with their talismanic forward, but Rooney himself is looking to keep his options open until after the 2014 World Cup.
With the Red Devils in serious danger of missing out on a top four finish after a disappointing opening half of the campaign, the possibility of the 28-year-old opting against extending his stay at the club is thought to have increased.
When asked by the Daily Mail about Rooney’s future and the impact of potentially missing out on top level European football, Moyes said:
“We would have to wait and see what happened in that situation.
“I think if you look at his performances he’s certainly playing at his best.”
Rooney was linked with a summer move away from United after growing frustrated with life at the club, but multiple offers from Chelsea were knocked back.
