Chelsea are gearing up for their Champions League semi-final match against Barcelona on Wednesday.
It's going to be a tough match for the Blues, even though the first leg in Spain ended without any goals.
That 0-0 draw in Barcelona means that if Chelsea win they will go through, but their opponents are in pretty good scoring form too!
In their most recent match, against title rivals Real Madrid at the weekend, Barcelona won the match 6-2.
However, Barcelona are likely to be without Thierry Henry, suspended defender Carles Puyol and the injured Rafael Marquez.
The Blues are still without Portuguese pair Deco and Ricardo Carvalho, as they are both struggling with hamstring problems.
Barcelona striker Thierry Henry may miss the match with an injury
However, Michael Ballack will return after being rested and Ashley Cole is back after being suspended for the first leg.
The match is being played at Chelsea's home ground Stamford Bridge.
Chelsea aren't scared
Chelsea coach Guus Hiddink insists his team aren't scared of the Spanish side. The Premier League team became the first side this season to stop Barca scoring in a game.
Barcelona and Chelsea are no strangers to each other. It's the 10th time they are playing each other in the Champions League.
Whoever wins will play Manchester United in the final of the Champions League on the 27 May in Rome, Italy.
