The only game Kia Havartz have done well is the game against PSV Eindhoven in the Champions League group-stage, and  Arteta said in the post-match press conference that he was really connecting in cascade despite the fans reporting that they are starting to get fed up with his (Kia Havartz) performance.
I don't know what need to be done for this player Kia Havartz to get back to the form he had back then when Chelsea won the Champions League, up till this moment is like the man has lost it all, no goals or assist and he's not even playing well.
Is it that Arsenal wasted money on this man Kia Havartz or does he need more time to prove him self?
