Chelsea will take a 1-0 win at Stamford Bridge into the second leg and could really put Barcelona under pressure if they score first and grab a crucial away goal.
Barcelona will fancy their chances facing just a 1-0 deficit and having the luxury of playing at home, where they are a very difficult club to beat.
However, the last three meetings between these clubs at the Nou Camp have ended in a draw, and if that happens again, Chelsea will advance.
Chelsea will have to defend to perfection on Tuesday if they want a positive second-leg result that sends them to Munich for the Champions League final in May.
Let’s look at everything you need to know so you don’t miss a minute of the intense action from the Nou Camp.
Terry desperately wants to get back to the Champions League final and win the competition after his penalty kick miss in the 2008 final could have won Chelsea the European crown.
Terry is a fierce leader and a spectacular one-on-one defender who needs to make sure his back four is focused and ready to face a determined Barcelona attack.
Expect Terry to lead an inspired Chelsea defense in the second leg at the Nou Camp.
