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…Ex-Liverpool coaches set for Feyenoord return Former Liverpool coaches Giovanni van Bronckhorst and Sipke Hulshoff are closing on a return to Feyenoord as the club’s new management team.Van Bronckhorst was assistant coach to Arne Slot at Anfield along with Hulshoff.The 51-year-old former Rangers and Netherlands midfielder also had interest from Besiktas.The appointment marks a full-circle moment for van Bronckhorst, who first took charge at the Rotterdam club back in March 2015.Millwall bid £5m for Hull forward – who manager likened to Messi!Millwall have launched a £5million bid for Hull City forward Kyle Joseph.The 24-year-old scored eight goals on the way to promotion last season, two of which were in a 3-1 win over Millwall at The New Den. Joseph has also professed that his father is an avid Lions fan.The Scotland U21 international can play across the frontline and has plenty of other suitors from the Championship.After a splendid solo goal against Southampton, Hull City manager Sergej Jakirovic said, part tongue in cheek, that it was like watching Lionel Messi in action.However, having secured a dream promotion to the Premier League with Hull, the main question will be whether Joseph wants to give that chance up for potentially more regular game time elsewhere. Kyle Joseph (right) in action with Middlesbrough’s Matt Targett last seasonHull know they have to upgrade across their team so face some tough calls on players who have served them well.Millwall lost to the Tigers in the play-offs after an impressive campaign and are looking to immediately bounce back into the promotion frame next time out.Crucially, Joseph suffered a season-ending ankle injury in Hull’s play-off win over Millwall which will need a 10-week recuperation period, meaning he will not be ready for the start of pre-season.Everton will go back in for Hackney after Boro turn down £18m bid Everton are expected to return to negotiations for Hayden Hackney after Middlesbrough rejected their latest offer of around £18million.Crystal Palace are also expected to make their move as Boro hold out for £20m plus £5m in bonuses for the Championship Player of the Year.Everton know Hackney wants to join them but Boro have been holding out for a greater sum in guaranteed payments.Daily Mail Sport understands Everton’s bid was around £11million with a further £7m in bonuses.Hull City have also expressed interest in meeting Boro’s valuation but Hackney’s preference is to link up with David Moyes’s side. Hayden Hackney was named Championship player of the season Boro agreed to sell for less from Ipswich Town last year but they believe Hackney has improved as a player since then, despite only having one year remaining on contract.Crystal Palace, who have appointed Pierre Sage as their new boss, have indicated they will come closer to £20m.Everton have interest from Ipswich in their midfielder Tim Iroegbunam and are still to finalise agreement with Idrissa Gana Gueye on a new contract. Cucurella seals Madrid move Chelsea have confirmed their £51.8million sale of Marc Cucurella to Real Madrid – £47.5m plus £4.3m in add-ons – all hastily agreed and completed at the request of new Madrid manager, Jose Mourinho. ‘Everyone at Chelsea FC would like to thank Marc for his efforts during his time at the club and for the role he played in our recent achievements,’ read a Chelsea statement. ‘We wish him every success as he begins the next stage of his career.’Kieran Gill Newcastle step up talks for Munoz – with Osasuna holding out for £34.5mNewcastle United are expected to step up negotiations for Osasuna winger Victor Munoz this week.Despite reports, those close to the deal say Real Madrid do not intend to take up a buy-back clause nor do they want a new clause inserted after he has spent a year at his next club. They believe no ambitious buying club would accept those terms.The 22-year-old is with Spain’s squad in USA and has opened the door to a move to the Premier League though there is rival interest from Roma and Bayer Leverkusen. Manchester United have not followed up any interest, as it stands.Munoz is represented by Niagara Sports agency, who also look after the likes of Barcelona’s Dani Olmo and Joan Garcia plus Alvaro Morata at Como.Though discussions have taken place with Osasuna they have yet to fully develop and progress is anticipated this week. Victor Munoz’s buy-out clause is £34.5m and Osasuna want the full amountThe Spanish side want £34.5million, the player’s buy-out, and Newcastle are looking to structure the payments.Munoz began his youth career with Barcelona’s famed La Masia academy before moving to Real Madrid.Newcastle want to add younger players going forward with the likes of Wolves’ exciting 18-year-old Portuguese attacker Mateus Mane also on their radar.They also want Atalanta right back Marco Palestra but face serious competition for the £45m-rated Italy international.As reported by Daily Mail Sport in April, Manchester City’s James Trafford is also back on their list despite the addition of Reims keeper Ewen Jaouen for £18.5m last week.Meanwhile, head of recruitment Steve Nickson is not expected to move to West Ham, despite reputed interest.Premier League new boys in for Braga stopper Hull City have opened talks for Sporting Braga goalkeeper Lukas Hornicek.The Premier League new boys want two keepers for their return to the top flight and are understood to have offered £12.5million plus add-ons for the 6ft 6ins Czech Republic international who is part of his country’s World Cup squad.The 23-year-old is interested in the move but Braga want more for a keeper who has also attracted interest from Leeds United, Inter Milan and Porto in recent months.Hull also want to add a second keeper on loan. Braga goalkeeper Lucas Hornicek is at the World Cup with Czech RepublicThey made a bold enquiry for Bayern Munich’s Alexander Nubel, but he is holding out for a bigger club.The 29-year-old was on the bench for Germany in their 7-1 win over Curacao last night and has spent the last three seasons playing regularly for Stuttgart in the Bundesliga while previously enjoying two seasons on loan with Monaco.Hull have sent scouts to the World Cup and are also exploring the Croatian market.They would like to discuss a deal with Manchester United for Toby Collyer, who they had on loan at the end of last season.It is felt the 22-year-old would benefit from a full pre-season, and develop into a midfielder capable of making an immediate impact in the Premier League.
