Manchester City are ready to boost the capacity of Eastlands to 65,000.
The News of the World says the project to make Eastlands the second biggest ground in the Premier League could be completed by the 2011-12 season. The stadium currently holds just under 48,000. Old Trafford seats 76,000.
A source said: "There have been rumours floating around the construction industry for a few months that City are looking at how to expand the ground.
"The owners are looking into it but there are a few obstacles to get through before they can get any work started."
