Now Barcelona having two home games first against Inter and then Bayern Munich which is not easy but if they are able to have one win from these two games then surely they can go with good result into second round because they have one game which is against Plzen and this can give them good win as well so right now most important thing is they have to win first match against Inter because this will give them a good confidence for staying into hunt for qualifying into next round.
With most chances Bayern Munich is going to be stayed as group leaders now fight is going between Inter and Barcelona which is surely favourable for Barcelona because they have better squad and quality for doing good performance and having good chance for qualifying into next round.
It is at least home games, I mean Inter should be easier, but there is a lot of pressure on them now, if they lose then they can say goodbye to UCL and go to Europa which is not enough for them, even if they somehow win it, which would still be very tough, it wouldn't be good enough for their financial situation.
On the other hand, if they somehow beat both of them at home, and of course beat Plzen, then they would be able to go up very easily, and they would face someone easier. That’s going to be a key difference here, and I believe that they are going to play as hard as they possibly can in order to win. It will be difficult, but something Barcelona can achieve for sure.
