I find the rumour that he's available for 21m hard to fathom.
It's not long since Aulas was publicly saying 50m wouldn't be enough
Me too - I'm guessing two things -
1) Lacazette has told him he'll leave once his contract runs out, so he is desperate to sell and there aren't so many teams interested for whatever reason
2) He is trying to get people interested - i.e. a bidding war - and has leaked a low price to the press to get clubs to get curious.
