Arsenal hold talks over signing Victor Osimhen amid interest in Gabriel Martinelli and Ethan Nwaneri - as Barcelona prepare fresh bid for Rodri: 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...

Arsenal have discussed signing Victor Osimhen during talks with Galatasaray over the potential sales of Gabriel Martinelli and Ethan Nwaneri.

Galatasaray made a £38.5million verbal offer for Martinelli, but the 25-year-old Brazilian is reluctant to leave London.

Nwaneri, 19, meanwhile, is assessing his options and, as it stands, talks for Nigeria striker Osimhen have not progressed.

Victor Osimhen's name was discussed by Arsenal transfer chiefs this summer

Martinelli has also had tentative interest from Paris Saint-Germain in recent weeks, but the French side have now turned their attention to Ajax’s Mika Godts, 21.

England Under-21 international Nwaneri was frustrated with a lack of game time last season, but has interest from AC Milan, Fulham, RB Leipzig and Borussia Dortmund, among others.

Arsenal are also in talks with West Ham over the £3m sale of winger Reiss Nelson, and Napoli want striker Gabriel Jesus.

There is interest from Hamburg for Fabio Vieira, and fellow midfielder Martin Zubimendi is on the radar of Jose Mourinho’s Real Madrid.

Barcelona are drafting a new proposal for Manchester City midfielder Rodri after their second offer was rejected. City are holding for closer £68m for the Spain captain.

Rodri was spotted by fans travelling back to Liverpool airport on a Ryanair flight from Madrid on Thursday evening.

City have rejected two bids from Barcelona for the midfielder, the second of which was around £55m.

Manchester United and Everton are continuing discussions over the transfer of Ethan Wheatley.

The 20-year-old striker is viewed as one for the future by Everton but will be able to have an impact in the first team.

The England Under-20 international is 6ft 3in and regularly clocks 36km/h in sprints. He has been on loan at Northampton Town and Bradford City in recent seasons and was a prolific scorer through youth levels at United.

Tottenham full back Djed Spence arrived in Milan last night ahead of his £26m move to Inter.

The 26-year-old has started his medical tests at the CONI Sports Medicine Institute this morning.

Will Smallbone has emerged as a target for West Brom. The 26-year-old midfielder is a free agent after leaving Southampton.

The Republic of Ireland international has a number of options but Albion have emerged as they are losing Alex Mowatt to Derby.
