depends how much you know about chelsea and your afinity to them. new stamford bridge would do (plus its the only stadium they have ever played in, so could keep the "name" for this reason.
maybe have a look at their wiki page for ideas.
here's some;
matthew harding stadium (helped save them financially)
rising sun stadium (their original name i think-double check though)
ted drake arena
the jose mourinho "i am the special one" shrine
the blues theatre
royal blue park
Ukhta stadia (Roman Ab's hometown)
