Well there is the rub with Giroud innit.
He is the footballing personification of the phrase that “absence makes the heart grow fonder”. Remove him from the starting 11 and his brief cameo appearances make you think “ooh he should start”, and then he starts and his deficiencies within the team system come to the fore.
He’s a sub, nothing more. A reserve to be rolled out when others need a rest in lesser competitions.
