Yes there are two big games Arsenal vs Chelsea and Tottenham vs Liverpool. Arsenal's current mentality is good, a string of wins and interim leaders of the EPL give them confidence. But chelsea's opponents are certainly not easy. Even though they lost to Brighton it was not a benchmark. Arsenal have to be careful, maybe saa potter will make a surprise.
Arsenal have better form than Chelsea but they will have to pay more attention on the opponent. Chelsea have enough good players to compromise Arsenal's weakness and mistakes if Arsenal show them in the match. In this season, Arsenal and Arteta are playing not only good in general but also good in big matches. That is good for them to keep fighting for the Premier League title.
As for Tottenham, they will be the hosts. That's because they're with the supporters. Liverpool are also in a difficult time. They haven't been able to play well since Mane left. Nunez, who is expected to perform great, hasn't been able to do much until this week.
Tottenham in this season have worse contributions from Harry Kane and Son Heung Min. They are getting older and be affected by the coming World Cup. Only about 20 more days until the World Cup and star players like them don't want to miss it.
Nunez is improving and that is good for him as well as Liverpool. He still made some bad decisions, missed some opportunities but with improvements, at least he gives us belief that he won't be a failed transfer for Liverpool.
Mane departure actually has very negative impact on Liverpool operation generally. Klopp is still struggling to fix that hole by other players and by other formations.
