Why do Arsenal ‘undervalue’ their players?

The Gunners clinched a club-record deal worth more than £50 million to bring Lacazette to the Emirates earlier in the month.

 Arsenal have a poor way of selling players, probably the most poor in the whole league. We undervalue our own players! Which is a bit cliche.

Let’s just  evaluate how much other players from other teams are moving for. Walker for over £50m, Pickford moved for £30m? De Gea is valued at £65m? Yet we sold szczesny for mere £8M that's absolutely absolutely disgraceful.I mean I’d rather not sell him at that price after the stellar season he had.

 Then there’s Ox Chamberlain, we bought him for £16m and Palace are willing to pay that much for him. Not bad, but not good either. English players valuations are inflated na again how can we sell Chambers for just £16m when Walker went for over £50m.Poor business by Arsenal.

 As for Gibbs and Jack. No we should not let them go.Gibbs is a very useful player.I thought Kolasinac was signed to play as a left centre back in our back three.That means Gibbs should have stayed as cover to Nacho Monreal a very underrated and useful player.

 Wilshere? Although had an injury prone career there’s still hope for him and we can’t let him go simply because of how talented he is.
