Premier League summer transfer window: What your club still needs to do with one month to go

Arsenal have the bulk of their business still to do after bringing in Christos Tzolis for £34m as a Leandro Trossard replacement and Illan Meslier as a third-choice goalkeeper on a free transfer after his departure from Leeds.

The Premier League champions have ambitious plans to capitalise on their title success by targeting elite signings for the left-wing and central-midfield positions. Work has been done to explore the cost of potential deals for Brazil stars Vinicius Junior and Bruno Guimaraes.

Vinicius, who has entered the final year of his deal at Real Madrid, is one of the options Arsenal are considering along with PSG's Bradley Barcola and Atletico Madrid's Julian Alvarez after refusing to meet Aston Villa's valuation of top target Morgan Rogers.

However, Sky Sports News has been told Real Madrid are confident Vinicius will sign a new contract and he is not expected to leave this summer. The Brazilian is entering the final year of his deal, and Arsenal continue to monitor his situation.

Arsenal want to sign Guimaraes to bolster the midfield, and he has told Newcastle he would like to join the Gunners. Discussions have taken place through intermediaries about the figures it would take to do a deal, but Newcastle do not want to sell.

Arsenal also have big plans to raise funds from outgoings, an area in which they have historically struggled, with uncertainty around the futures of Gabriel Martinelli and Gabriel Jesus, who is valued at £18m-£20m, as they enter the final year of their contracts.

Martinelli's deal includes a club-held option for a further year, protecting Arsenal from losing him for nothing in a year should the right conditions for a sale not materialise this summer. It is unlikely that his sale would be sanctioned without the arrival of another left-winger.

Ben White has attracted interest from the likes of Everton, but injuries to Jurrien Timber and William Saliba could impact Arsenal's willingness to let the England defender go. It remains to be seen if Timber is going to be fit for the start of the season.

Arsenal are exploring options at centre-back in light of the news that Saliba's back injury would keep him out for an extended period. John Stones was under consideration but has joined Inter, while there is a gap in valuation with Aston Villa for Ezri Konsa.

Johan Manzambi, Joao Gomes and Alejandro Garnacho have arrived to bolster Unai Emery's squad ahead of their return to the Champions League - but more numbers are needed with the futures of Leon Bailey and Emiliano Martinez also uncertain.

Hull City are close to signing Bailey, who has one year left on his deal, while links to Juventus for Martinez refuse to go away. Juve are exploring alternatives due to the gap in valuation, one of which is Zion Suzuki, who is on Villa's keeper shortlist in case Martinez goes.

Villa are one of several clubs in the Premier League and Europe to express interest in Chelsea striker Nicolas Jackson but will be unable to loan him from Chelsea, having already signed Garnacho on a temporary deal, and a permanent move is complicated by UEFA's rules.

There is also interest in a temporary move for midfielder Joao Palhinha, but Bayern Munich want a permanent deal for the 31-year-old, who spent last season at Tottenham. Benfica and Palhinha's former club Sporting have also been interested in a summer move.
