Tottenham Hotspur have made an opening move for Galatasaray striker Victor Osimhen, submitting an approach worth up to £55 million for the 27-year-old Nigerian international. However, Galatasaray are holding firm, valuing their striker at closer to £65 million, according to Caught Offside.

The Osimhen pursuit is the headline act in a busy summer window, with several other significant deals taking shape across the Premier League and beyond.

Guimaraes set for Arsenal switch

Bruno Guimaraes is reportedly on the brink of a move to Arsenal, with the Newcastle United and Brazil midfielder, 28, set to undergo a medical at the Emirates in a deal worth nearly £80 million, per The Athletic.

Gakpo talks and Grealish interest

Tottenham have also held positive preliminary talks with Liverpool forward Cody Gakpo, though the Reds have made their position clear — the 26-year-old Dutchman is not for sale. Elsewhere, Atletico Madrid are weighing up a move for Manchester City winger Jack Grealish, 30, with Everton and Aston Villa also understood to be exploring bids for the England international, according to The Sun.

Keeper and defender deals near completion

Newcastle look set to secure a second piece of business after Braga goalkeeper Lukas Hornicek, 24, completed a medical. The Czech Republic international's £25.7 million release clause has reportedly been triggered, per the Daily Mail.

Hull City are closing in on two separate signings: Nice striker Mohamed-Ali Cho, 22, for around £17 million, according to L'Équipe, and Australia defender Lucas Herrington, 18, from MLS side Colorado Rapids for the same fee, per The Sun. Hull are also poised to pip Rangers and Cardiff City to the signature of Norwegian midfielder Jens Hjerto-Dahl, 20, from Tromso, according to the Daily Mail.

Chelsea improve Chavarria bid

Chelsea have returned with an improved offer for Rayo Vallecano left-back Pep Chavarria, 28. After the Spanish club rejected the Blues' opening bid of £12.8 million and demanded £21.4 million, Chelsea have now submitted a revised proposal, per Teamtalk.

Real Madrid pair head to Fulham

Finally, Real Madrid duo Gonzalo Garcia, 22, and Cesar Palacios, 21, have been undergoing medicals at Fulham after the London club reached an agreement for permanent transfers of both the Spanish striker and midfielder, according to Sky Sports.
