manager Mikel Arteta seems intent on addressing his side's shortcomings early.There should also be plenty of finance available for him to finally bring in a prolific centre forward to get Arsenal over the line in competitions - a bone of contention among supporters.

Record revenues of £616m in 2023-24 are likely to be exceeded thanks to the expanded Champions League format and extra broadcast revenue, while the sales of homegrown duo Emile Smith Rowe and Eddie Nketiah in the past 12 months brings about £50m of pure profit."As the most profitable club in Premier League history, Arsenal could easily spend over £200m in the window and have no PSR concerns," said Maguire."So if a striker is not signed it cannot be blamed on PSR."

Having failed to qualify for the Champions League things look less rosy at Aston Villa.The club made a loss of £206m in the two years to 30 June 2024 and, with the £100m departure of Jack Grealish in 2021 dropping away from their PSR figures, backing Unai Emery will be far from straightforward.

Last term's run to the quarter-finals of Europe's elite club competition, along with the sales Moussa Diaby, Douglas Luiz and Jhon Duran will undoubtedly have helped.

But the Midlands club has spent more than £900m since returning to the Premier League in 2019, exceeding Uefa's 70% revenue to wages ratio every season.However, late on Wednesday, the US Court of International Trade ruled that he had exceeded the authority of the emergency powers he was using. The court gave the White House 10 days to remove almost all tariffs, which it says have been imposed illegally.

The White House appealed, and a federal appeals court has stayed the trade court's ruling, which means that those tariffs will stay in place - for now.The administration argued in its appeal that a ruling against Trump "would kneecap the president on the world stage, cripple his ability to negotiate trade deals, imperil the government's ability to respond to these and future national emergencies".

On Thursday night, Trump was back on Truth Social, rebuking the lower court judges who had ruled against him, calling their decision "wrong" and "horrible".Until now, the power to make or break the economy has rested on his shoulders, as the tariff rates levelled against other countries keep going up and down – seemingly according to Trump's mood.
