“I don’t think Robin will play on Wednesday,” Moyes said in a press conference on Tuesday. “But I think he’ll have an outside chance for Saturday [against West Bromwich Albion].”
While some websites are taking Moyes’ words as confirmation that van Persie is out, it’s worth noting that Moyes’ soundbite doesn’t rule out the possibility of the striker featuring.
This, combined with the fact that it was only two weeks ago when Wayne Rooney was reportedly out due to a head wound, only for the Englishman to feature the next day against Crystal Palace
