From Giroud’s perspective, he is at a club he knows, with a manager that has stuck by him for more than five seasons, even though he has limited ability, and he isn’t going to go to another club that has a chance of playing CL football.
He probably also prefers London to living up North.
He would have done well at Everton, and would have started most games, but realistically he is at a club that is bigger than any other he could go to, so he has probably made the right choice.
From our point of view, he is one of the best second choice strikers in the PL.
It’s just a shame we had to wait for so long to get a first choice striker to make him second choice.
