I believe that we have competition and we want to compete in all competitions with the best moment of the players that we have at our resource, and thats what we try to do.But those comments obviously raise the question of whether or not Kepa Arrizabalaga will come into the side for Wednesdays trip away to Chelsea.Photo by Clive Mason/Getty ImagesThe general public largely consider Kepa to be Arsenals cup goalkeeper, suggesting hell be favoured over David Raya for Wednesdays League Cup semi-final even if Raya is first choice in the Premier League.But if Artetas comments are true, then hell just be picking the best man for the job on Wednesday night.When pressed on this particular point, Arteta confirmed that his primary focus is on winning the game, though he did add that goalkeepers are a bit of a special case.Well its because at the end our job and my job is to prepare the team the best possible way to win the competition, every competition that we are in, Arteta said.Every game is different, every game requires different qualities and players, and players have moments when they are really high, when they dont have much confidence and minutes and every case is different.The keepers on top of that is a very particular case as well, because obviously they have less opportunities than other players to play throughout every week. But we try to treat them in that sense.Photo by Yong Teck Lim/Getty ImagesKepa has generally done a good job for Arsenal when called upon so far, with the possible exception of the goal he conceded to Portsmouth at the weekend.But Raya is widely considered one of the best goalkeepers in the world, so its hard to argue the Gunners wouldnt benefit from having him between the posts for this semi-final.Its a tough decision for Arteta to make, and his lineup on Wednesday night will probably tell us more about his cup keeper philosophy than his press conference has.
