Arteta does have to work extra to match Manchester City because after all, Manchester City is very consistent in its matches, I mean it doesn't always make blunders in pursuit of victory, we will see how Arsenal can maintain its position at the top of the table and how Manchester City can win the match for three points to stay in the competition at the top of the table, we know City is a Lion in addition to being at home, of course it will benefit Manchester City.
Yes, of course Klopp expects the Man City vs Arsenal match to end in a draw, but Liverpool will compete against Brighton, I know Brighton is also quite strong, but I am much more confident that Liverpool will get 3 points in the match against Brighton.
Yes this season will be a tough test for Arteta to be able to deliver something that Arsenal fans have long coveted namely the Trophy, but it is not easy for Arteta to make that happen when they have to compete with Liverpool and Manchester City, what you say is true because after all this is a crucial time for Arteta and he must be able to bring out all the skills to be able to give his best for Arsenal, so far the pupil have beaten the teacher in their first game of the season, and it is important for pupil (arteta) to beat teacher (Pep Guardiola) again in the second meeting this weekend to keep Arsenal's chances of winning the trophy this season alive.
Honestly for the Liverpool and Brighton matches, I personally might see Brighton will be able to surprise Liverpool in the match later, indeed so far the draw between Manchester City and Arsenal is what Liverpool expect, but they should be more focused on winning the game against Brighton which has often given nightmares to Liverpool no matter it is home or away and my prediction Liverpool and Brighton may also have the potential to draw the game later.
