Chelsea now has a perfect No9, Already lukaku would had scored twice but the second chance was not given to him. I am predicting a three to four goals scorelines as I am still waiting on lukaku to score more goals. Everybody in the Chelsea squad is playing well except for few mistakes that almost caused an own goal by jorginho.
Lukaku is a very talented striker and I believe he will succeed in the second contract in Chelsea.
However, it is not wise to judge his success in the future after a few first matches for Chelsea. In the past, Morata had some early good matches for Chelsea but finally he is a failed transfer in Stamford Bridge. With striker, a few bad matches might take all of confidence out and when a striker plays without confidence, goals will be very hard to find.
Arsenal need to bring in their A game if they want to get something from this game. The best they can do is a draw but I doubt Chelsea will let that happen keeping in mind they will be paying Liverpool next and that game would be a though one. They need this three point and they will make sure they secure it with more goals.
Arsenal seems to have another bad season. They have very bad early matches in Premier League and it seems the summer does not help them to improve anything.
