Newcastle needs to do that caused by it will be facing another important match against PSG soon. The club needs to improve it but the most interesting to see that if newcastle was scoring 8 goals with different players.
There's no player that made more than 1 goals. 8 goals divided to all of players which is amazing. Newcastle is stopped to be wasteful in any chances.
Howe was trying 4-3-3 which was perfectly fit to the newcastle. I hope newcastle can steal three points from PSG soon.
Haha Newcastle are too confident they don't miss any opportunities convert every opportunity into a goal

as you said they need to do this to increase their confidence in the Champions League. Slowly Newcastle are getting back on track, this is their 2nd win after a bad result a few weeks ago they have to do something like this in the next match to regain their place in the top 4 they are already 5-6 points behind the top 4.
