He's improved undoubtedly and he's surpassed my expectations of him (though they were admittedly rock bottom when we signed him). He does have some value. The issue is, we've put him on a huge contract with large financial outlay and when his terms are (likely) up for renewal next Summer, he's probably going to want an increase in pay (as every person in their line of work normally would). Can you honestly sit there and tell me it's worth giving him £300k a week and a 4/5 year extension? Because I think it would be a big mistake if we did.
I don't know what type of crack the negotiating team were smoking when they signed Havertz, crazy transfer fee and even crazier wages ! Considering at the time we were buying essentially a dud from Chelsea. He has proved his worth at Arsenal, I guess we will have to play it by ear when it comes to renewal time, how is he performing, what other options are there out there, etc.
