Bruno Guimaraes in London to finalise £75m move to Arsenal after leaving Newcastle training camp - as Forest move for Ousmane Diomande reaches an impasse: WINDOW WATCH

It's that time of the year again – the transfer window is now open until September 1 and it's sure to be a busy period with clubs looking to make big signings ahead of next season.

Here are today's latest developments from Simon Jones and the Daily Mail Sport team...

Ousmane Diomande's move to Nottingham Forest has hit a major snag with the deal now far from certain.

Forest had been close to agreeing a fee of about £35m with Sporting Lisbon for the centre-back but Daily Mail Sport understands talks have hit the buffers.

Oliver Glasner had made the centre-back his top target - as he did at Crystal Palace last summer, which also proved unsuccessful.
