So all the big newspapers like Daily Mail; Sky Sports; The Guardian and others got this interesting article saying that: 

Fergie wants Lampard... and Chelsea legend is ready to talk to United" 
Sir Alex Ferguson is considering a sensational move for unsettled Chelsea midfielder Frank Lampard. 
Sportsmail understands Lampard would not be averse to a switch to Old Trafford. 
With United struggling for numbers in midfield and desperate to make sure Sunday's FA Cup opponents Manchester City do not leave them behind at the top of the Barclays Premier League, manager Ferguson is weighing up an offer for a player he has always admired.

Speculation: There's an interesting piece of speculation to get us started today, with Manchester United reported to be planning a £10million bid for Chelsea's Frank Lampard as they look to bolster their ailing midfield, with Red Devils chief executive David Gill said to have sounded out the Blues.

It would never happen. Lampard doesn't care about the money, he's at the club because he's loyal to Chelsea and their fans.

Lampard would NEVER do that, like nandaYNWA said he doesn't care about the money, he is a player that respects Chelsea and Chelsea respect him, thats just a stupid rumor

Thats not gonna happen in a million years he shall stay a true blue forever

It's a complete rumour. Sir Alex himself has confirmed it. Here

Lampard himself said that he wants to stay at Chelsea and here's what Sir Alex had to say:

"What can you get in January?" Ferguson said. "The players we'd like,
we can't get. If the alternative is to sign a second-rate player, we
don't want to do that.

"Our injuries have led to fans wanting us
to sign someone but I don't want to sign a player who won't get a game
when everyone's fit because he's not good enough."

he will not go .

Sorry Chelsea fans but Chelsea are now seriously considering transferring Lampard but not to a Premier League team. All this because of a rift between him and Villas Boas. Also Higuain is being targeted to serve as a replacement for Drogba in the future.

it has the same probability for Rooney to be transfered to City... both of them are not going to happen. Why would lampard who is a club player with all his history behind in Chelsea would be going to Man Utd.?

Lamps is not worth 10 million... he is worth waaaaaaaaaaaaayyyyyyy moooooooooooorrrrreeee
