Arsenal have strengthened their squad in the summer transfer window and the knock-on effects are now being felt by Mikel Arteta, with one of his squad players unsettled

Johnny Cardoso's long awaited move from Real Betis to Atletico Madrid is reportedly almost done. The two sides have reportedly agree a transfer package of around $35 million, per Fabrizio Romano, which just might be the most high-profile move a U.S. men's national team player might make in the year before the World Cup on home soil.

Mikel Arteta has said he hopes Viktor Gyökeres can have a transformative effect on Arsenal after his €63 million ($74m) move from Sporting CP.
