Arsenal may have inadvertently announced their fifth summer signing after an image of Cristhian Mosquera was accidentally posted online.

Arsenal’s decision to sign winger Noni Madueke from Chelsea in a £52 million ($70m) transfer continues to generate waves of discussion and none more vocal than that of former club star Paul Merson. The ex-midfielder has admitted he’s “flabbergasted” by the club’s latest move in the transfer market, raising questions not only about the player’s ability but also what it might mean for fan-favourite Bukayo Saka.

Noni Madueke has revealed he wants to "win it all" and help Arsenal "take that next step" to silverware. The Gunners shelled out £52 million (€60m/$69.9m) for the winger, who has signed a five-year contract at the Emirates Stadium. The transfer was finalised on Friday, sending a clear message about the Gunners' ambitions for the upcoming season.
