Despite agreeing the basic framework of a move for Gyökeres weeks ago, Arsenal and Sporting found themselves butting heads over the nature of the add-ons proposed by the Gunners, which invited pressure of a potential hijack from long-term admirers Manchester United.

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 said he was happy that Arsenal had signed a number of top-quality players in the early stages of the transfer window, and that they had given the Premier League club impetus to raise their level in the coming season.
