Celtic could only manage a draw against Benfica in their first game, which isn't the worst result, but seeing as their next two matches will be a double-header against Barcelona, they will see a victory tonight as vital to get three points before playing arguably the best football team in the world.

A loss tonight would leave the Scottish side with just one point going into their Barcelona clashes, and with most analysts predicting two wins for Barcelona, they could potentially be just one point from four games and on the verge of elimination.

Celtic could miss right back Adam Matthews for today's clash. Matthews traveled to Russia with his ankle in a protective cast and is doubtful to make the starting line up.

Meanwhile, Spartak Moscow will be in confident mood today - having pushed Barcelona all the way before finally losing 3-2 in the Nou Camp, they will fancy their chances at getting the victory against Celtic in front of a home crowd.

Spartak will be without first-choice goalkeeper Andriy Dykan, who was reported to have damaged his shoulder. The Russians will also be missing captain Sergei Parshivlyuk, Brazil international midfielder Romulo and leading striker Welliton.

The injury list for Spartak does not end there; Evgeni Makeev, Nicolas Pareja, Marek Suchy and Kirill Kombarov are also injury concerns for the Russian side.

Since losing to Barcelona in Spain, Spartak have won three domestic games in a row, and have moved up to fifth place in the Russian league - just four points adrift of leaders Anzhi Makhachkala.
