Olympiakos ace Tresor Lomana LuaLua is hoping to win his fitness battle to face Chelsea this week.
The former Newcastle and Portsmouth forward is struggling to make Tuesday's UEFA Champions League clash as he looks to shake off a niggling injury.
LuaLua is set to undergo a fitness test on Monday and the mercurial forward is determined to prove his fitness to face Avram Grant's Chelsea.
"This is my last day to actually train today to see if I will be able to make tomorrow," LuaLua told Sky Sports News.
"I am hoping it goes well as I really want to play in this game tomorrow."
LuaLua believes Olympiakos can shock Chelsea when the Premier League side travel to Athens.
"We really have nothing to lose," added LuaLua. "We are not the favourites.
"It is one of those games you do not get to play every day. It is one of our biggest games of the season and we have got to enjoy it really and give it our all."
