Vs Barcelona will be a challenging match for them, but not only for them but this must also be difficult for Barcelona. Although not the same, I think their appearance in the Champions League has its own similarities and in terms of goal productivity is not much different.
Another advantage is that they will play as hosts which will be a good thing for Borussia Dortmund. But the problem lies in the opponent, yes Barcelona will not be that easy to beat even though they play as away team status.
I hope this match will be very interesting and provide an entertaining spectacle for us.
I think Barcelona is not under much pressure in the Champions League platform now. We have seen Barcelona win four consecutive matches. Barcelona started the Champions League with a defeat. But due to winning four consecutive matches, Barcelona is currently in third place in the points table. So even if they lose one match, Barcelona will not face any major loss at the moment. However, Barcelona's main target is definitely to be in the top 8 of the table.
It is definitely difficult for Barcelona to win against Dortmund. Dortmund is performing quite well in this season of the Champions League. Dortmund is currently in fourth place in the points table. Dortmund has not faced any strong opponent other than Real Madrid in their 5 matches. And Dortmund lost against Madrid by a big margin of 5-2. Apart from that, Dortmund has played against teams like Celtic, Club Brugge and Sturm Graz. These teams are quite weak. So Dortmund got an easy win. It is also very difficult for Dortmund to win against teams like Barcelona and Madrid.
