Baines is being linked with United as a successor for Patrice Evra.
"I've been aware of what's been said in the press but I don't know much beyond that," said Baines, who still has three years left on his present deal.
"It doesn't do any harm (to be linked) but it doesn't do any good either.
"It's just one of those things that tends to swing around this time of year. People put two and two together sometimes they get four and sometimes they get three or five.
"It gets other people more excited than those involved."
