Barcelona will take to the pitch against Spartak Moscow on Wednesday night for the first match of their Group G fixtures.
The Catalan club will look to continue their winning form as they will host a Spartak Moscow side that has not made the Champions League for the past six years.
Barcelona is top of the Spanish La Liga and already eight points clear of their fierce rivals Real Madrid at this early stage in the season. However, for tonight's game they will be without a few key players that Spartak will look to capitalize on.
Barcelona Manager Tito Vilanova will have to find ways to fill the gaps left by Andres Iniesta and Carles Puyol. Both Alexis Sanchez and Jordi Alba are listed as doubtful for the match at the Camp Nou, where the Spanish side has not lost a Champions League match since October 2009.
"There's no use in looking back, not when you win or you lose," Vilanova told reporters during a press conference on Tuesday.
"In the Champions League we have to be attentive right from the start, our experience tells us so as we've had a tough time in the group phase before," he added.
All eyes will be on Lionel Messi as he continues to dazzle and delight fans will his amazing skills, ball control and of course goal scoring. Messi has scored six times in his last four matches already this season.
Spartak Moscow does have one advantage heading into Wednesday's match, their coach Unai Emery has previously managed Valencia and Almeria in Spain before leaving to take over Spartak. Unfortunately, Emery has yet to secure a result against Barcelona, having lost the previous 12 meetings against the Spanish side.
This is the first Champions League match for Spartak in six years, and they were able to make the elusive European tournament with the help of strong midfield play from Brazilian Romulo and Kim Kallstrom of Sweden. Spaniard Jose Manuel Jurado has also been a strength up front.
The match starts at 2:45 EST and will be televised live or can be watched online here.
