I really like Havertz and think he'll be great in this Arsenal team.
Transfer after transfer Chelsea keeps making even less sense, their midfield and striker options are horrible.
People might think 'OK, they will buy a few players' - sure, they might. But they cannot bring quality players without CL football so I don't expect them to fill these spots (Havertz, Kovačić) with better players.
Kova and Havertz were never better in those positions, and they both had awful final third passes. A player like Kova is not what we need in our midfield; he knows how to create a way from tight angles, but he was always offensively ineffective, with no pass vision and poor shooting accuracy. I'm glad we got rid of these two players for a good price in order to find a better alternative.
Chelsea is a huge team with a winning record; we don't need the CL to recruit good players; we can sign anyone who fits our system.
