Manager Mikel Arteta spoke about the addition, claiming that the move would enable them to bring in the best players swiftly. He said (via GOAL):"I think it's a big addition to the club, a big addition to the team. A team that is already formed with a lot of great people. Richard [Garlick] leading it, obviously. But as well with James [King], with Jason [Ayto], with a lot of people at the club that have been doing such good work. So it's about building out that chemistry. And I believe Josh [Kroenke] has been fully involved in the process as well. So we are all very excited to have him. You just met him, and straight away the words that come out are always winning, improving and demanding.""And he's a person who is very honest, very straightforward, with a very clear vision of what he wants to do. He was so willing to join us, which is a very positive thing as well because he had many other possibilities, and he's chosen to come to us. And now it's about us giving him the support and the understanding of the situation and context straight away. And for him to start to do what he's already done for many, many years at the highest level, which has been very impressive."Arsenal have signed Martin Zubimendi, Christian Norgaard, and Eberechi Eze for the midfield, while Noni Madueke and Viktor Gyokeres have been added in attack. They have also brought in Kepa Arrizabalaga from Chelsea, with Cristhian Mosquera being the lone addition in defence.
