Olympiacos striker Lomana Lualua is convinced they can take advantage of Chelsea's shaky defence ahead of their Champions League clash.

LuaLua, formerly of Newcastle and Portsmouth, said: "I watch a lot of Premier League football and Chelsea are a fantastic team - but they are not unbeatable.

"They have some world class players like Drogba, Lampard and Anelka but I fancy my chances against their defence, especially if John Terry is not fit.

"We've already drawn with Real Madrid and beaten Lazio so we do not fear Chelsea. I believe we'll go through to the quarter finals."
