Chelsea has a very strong team this season with the additions of Havertz and Werner making it superb.
Giroud scored 3 perfect goals and he showed that he is a classy striker (in my opinion a bit of underrated during his football career). Sevilla seemed unable to win the game as their defense was out of position every time Olivier was moving in order to get the ball.
The internal competition for the official striker position in Chelsea is very interesting race between two good strikers: young and old strikers. Tammy Abraham is younger the Giroud and he had very good first half of last season. In the second half of last season, Tammy lost his form and position over Giroud. This season, it seems Werner joined the race in early matches but gradually Lampard found the best position for him. Then again the race is between two guys, Giroud shown his ability and makes the competition is unpredictable.
ManUnited and Leipzig have to fight over each other because their points are the same and the week to come will be the decisive match, therefore both have pressure because they have to be able to win until the final match
It's playing away for ManUnited and usually away is much better to have played on its own before, I also believe in the Manchester squad that is going to go all-out and this will make for a more interesting match for us to see.
Not only that, in Group B there are still many teams that have a chance.
Leipzig slipped a lot compares to their performance last season but Manchester United has their own serious tactic problems and too much dependence on Bruno Fernandes. Anyway if I have to make a choice, I will choose Man Utd.
