Arsenal has been quite active in the transfer window this summer. The Gunners have already secured the services of Nuno Tavares, Albert Sambi Lokonga, and Ben White so far.But Mikel Arteta believes his squad still requires a few more changes to get back to their best next season.Arsenal is planning to offload players who do not fit into Arteta’s plans. The Gunners are looking to strengthen their midfield as well as their attack ahead of next season.On that note, let’s take a look at the major Arsenal transfer news from August 1, 2021.Arsenal risk losing five players worth £60m for free next summerAlexandre LacazetteArsenal need to offload five players this summer, or else they risk losing them for free next year, The Express reports.Alexandre Lacazette, Sead Kolasinac, Calum Chambers, Eddie Nketiah, and Mohamed Elneny are all worth a total of £60 million, and all of their current contracts expire next year.None of the five, however, are part of Mikel Arteta’s plans for the upcoming campaign, so the Gunners are in a hurry to offload them before the end of August.Arsenal value Lacazette, who has struggled in recent times, at £25 million. With Arteta pushing for a new striker this summer, the Frenchman’s time at the Emirates looks over. Kolasinac, like Lacazette, is not wanted at the Emirates, and the Gunners could let him leave for £6 million.Chambers appeared just 20 times for Arsenal last season across all competitions, and the arrival of Ben White will further limit his chances. The Englishman is available for £10 million this summer.Nketiah appeared 30 times for the Gunners last season, finding the back of the net six times, and will be available for £14 million.Elneny’s chances of breaking into Arteta’s team are bleak, too, and the Egyptian is valued at £4.5 million.Gunners preparing €30m offer for Brazilian starBruno GuimaraesArsenal is preparing a €30 million bid for Bruno Guimaraes, according to The Hard Tackle via Globo Esporte.

The Gunners are looking to add a new number nine to their ranks this summer, and Mikel Arteta is impressed by the American.The 20-year-old joined Schalke in 2019 and registered six goals and a solitary assist in 24 appearances for the Royal Blues last season.
