Kai Havertz is a good player, but I also think that the price that Chelsea and Arsenal paid for this player is quite high. When he was playing at Chelsea, he did not have stable performance, but there were times he scored decisive goals for Chelsea,one of them was helping Chelsea win the Champion League. Havertz's contribution to Chelsea is not small, so Arsenal noticed and bought this player even though there are always dozens of questions about Havertz's true form and class.
Kai Havertz has weaknesses such as his tendency to lose form for a long time and difficulty returning to form within 1-2 weeks. This is a big challenge for Arteta and Arsenal because they need a strong squad every week to compete fairly with Mancity. However, Kai Havertz has the ability to read tactics well, be creative, and be flexible on the field, and the fact that he can play in many positions could help Arteta have a quality complement to the injured positions.
Kai Havertz is still playing virtual number 9 position at Arsenal, but if Havertz plays in his right position is Second Striker, he will have Saka and Martinelli on the wings to support the attack, along with the flexibility of Jesus above can make Arsenal's playing style more variable and unpredictable.
Havertz wasn’t a player that had stable form even when Chelsea signed his from Bundesliga, he was just a player liked by then Chelsea’s coach Thomas Tuchel and as such he was brought to London. Though his form wasn’t stable you never can take away the fact that he was a player that had always helped Chelsea when it mattered most.
Arsenal saw this trait and they went on to acquire him, besides he was one player loved by Mikel Arteta and as such the club went all out for him. So it’s understandable the questions that surround the huge fee he was signed for as regards to his match performance of it is really worth that amount.
I think at Arsneal they have been able to note his weakness and then pair him with players who can help hom be able to get those goals. This has in turn be able to help him build up confidence and he was even able to get a brace against Chelsea and now having about 11 goals this season.
Havertz is a versatile player and as such, I think he can be able to play in any position he’s chosen to play and I think Arsenal is really one team that’s meant for his style. Havertz at Arsenal is way better than he was at Chelsea and I think his performance level has increased and as such, he’s been able to show us reason why he was signed at that price.
