My point was pretty clear but let me try again: there won't be much of a competition as Bastioni will be the undisputed starter. Bastoni - IF bought -is not bought to provide Davies with competition, he will automatically be (far) ahead of Davies.Davies will always have his spot in the squad. He's a very good squad player and the ultimate professional. Ranocchia, D'Ambrosio and Gagliardini found game time under Conte and they're not fit to lace Davies's boots, they're that mediocre.
But for sure Davies would be starting cup games etc. as he's shown to be a solid LCB this season.
