I'm pretty sure this is not the case. I work in London in a place called Imperial Wharf. This is where Chelsea put all their new signings and a lot carry on living here. I see Ramires, Lukaku and Juan Mata on an almost daily basis. Used to see Torres as well but pretty sure he has moved. Whilst Imperial Wharf is walking distance to Stamford Bridge, I'm pretty sure it would take longer than 30 minutes to get to their Cobham training ground. Could be wrong though.
