I think Newcastle will not lose this match. Either the match will be a draw or Newcastle will win. Newcastle's players are now brimming with confidence after beating PSG. They beat PSG by a big margin. However, defeating the Dortmund team will not be an easy task at all. This team is performing very well now. I watched Dortmund's performance against Werder Bremen today. The team is strong enough and the players are in good rhythm I guess the match will be a draw. Dortmund will definitely not want to lose. Dortmund are now at the bottom of the table. The team shared points with Milan after the defeat against PSG. Against Newcastle, they will try their best to get points.
I don't think Newcastle United will loss from bottom standings teams in Group F Dortmund who not winning one match yet in Champion League after playing two matches. St. James' Park as Newcastle United stadium have good memorize for Newcastle Unite after winning over from PSG last match, Newcastle more confidence continue the winning trend exactly for first participants in Champion League competition after absent longer time is great opportunity qualify to knock out round.
In Champion League, Dortmund not on top level performance although they good capital in domestic league after winning over Werder Bremen 1-0 and settled on 1st standings awhile. Newcastle United is difficult opponent for Dortmund and I don't sure with Dortmund opportunity get take three points.
There is no doubt that Newcastle team performed well in both matches. They played great. Newcastle's performance against PSG impressed me as they beat a big team like PSG very easily. But let's not forget that this team is not experienced enough. And for this reason, it will be very difficult for Newcastle to maintain the consistency of performance. On the other hand, Dortmund lost points in the first two matches but this team is strong enough. And Dortmund's performance in the Bundesliga is also quite good. The team will try their best to get points against Newcastle. Scoring points against Eddie Howe won't be easy. His match strategies are really good.
