Jose Mourinho insists he "doesn't lose at Stamford Bridge" and is confident his Inter Milan side can knock Chelsea out of Europe.
Mourinho returns to the club he managed for three years on Tuesday when the Serie A side aim to protect a 2-1 first-leg advantage in London.
The Portuguese coach believes his side can see off the Blues and hopes he again tastes success at Stamford Bridge - something he was very used to doing when in charge of Chelsea.
"Everybody knows Mourinho doesn't lose at Stamford Bridge," a typically confident Mourinho said ahead of the much-anticipated showdown.
"My record is unbeatable. It is amazing - we were so strong for such a long time."
Punters using their free bet could be influenced by Mourinho's views ahead of the game and will be tempted to back his side to come out on top.
Chelsea warmed up for the second leg with a 4-1 win over West Ham in the Premier League on Saturday but Inter were beaten 3-1 on Friday night by Catania and are now just a point clear of local rivals AC Milan at the top of the table.
