Manchester United will go on the road to Real Sociedad on Tuesday night in what is an important Champions League for United as they look to secure top spot in Group A and guarantee their spot in the knock out stages of Europe's top club competition.

The game is scheduled to kick off at 7.45 p.m. GMT and can be watched online through live stream via the link provided below.

United are currently top of the Group A with 7 points from their 3 games so far. As the second half of the group stages commences, United know that if they can win again today they will have one foot in the next round.

Real Sociedad have struggled so far this season in the Champions League with zero points from their three games. Although they have not been completely destroyed by any team, they have a goal difference of just minus-4 from their three losses.

They will be hoping to cause an upset against the traveling Manchester United team who have had a very mixed up and down season so far in the English Premier League.

United will be without defenders Jonny Evans and Rafael, with Evans, 25, out with a back injury while 23-year-old Rafael is absent with an ankle problem.

"We haven't had a lot of injuries," said Manchester United manager David Moyes ahead of today's game. "I think it's the best Manchester United have been in that respect for a while. But we did pick up three on Saturday, which is very rare - especially by half-time."

He said, "Two of them haven't travelled - Jonny Evans and Rafael - so they're not with us."

"I won't take anything for granted," added Moyes. "I have a lot of respect for Sociedad. We have to play well if we're going to get those 10 points, which will get us over the line. We've got ourselves into a good position in the group and we have to try to maintain that. I think our experienced players have shown they're used to the Champions League."
