Chelsea are on the verge of signing Mark Cukurella from Brighton after a bidding war with Manchester City. According to Sky Sports, the Blues have agreed a £52.5m deal with the Seagulls. Manager Thomas Tuchel needed reinforcements throughout the summer after Antonio Rudiger and Andreas Christensen left Stamford Bridge on free transfers. Meanwhile, Manchester United manager Erik ten Haag says it was “unacceptable” for Cristiano Ronaldo to leave Old Trafford before the end of Sunday’s friendly with Rayo Vallecano. Ten Haag told ViaPlay Sport: “Absolutely not. It is unacceptable. I told them this – that it is unacceptable. “We are a team, we are a team and you have to stay until the end.” And City have entered the race to sign RB Leipzig star Josko Gvardiol. According to Bild, City have already tabled a £66m bid for Gvardiol. The Citizens have been interested in signing the 20-year-old for some time before committing to an offer. However, Leipzig rejected the offer with no intention of selling the Croatia international. Also, United and Chelsea are “monitoring” Jamie Vardy’s situation at Leicester, while Ronaldo’s future remains uncertain. According to 90min, several clubs are tracking Vardy, including United and Blues. The striker has a year left on his current deal with the Foxes, where he has enjoyed tremendous success over the past 10 years. The 35-year-old club legend is yet to hold talks with Leicester over a new contract. Finally, Kasper Schmeichel has completed his shock move to Nice from Leicester. Schmeichel signed a three-year contract with the Ligue 1 side and completed 11 years at the King Power Stadium. The Foxes posted a lengthy and heartfelt tribute on the club’s website: “After 11 years with Leicester, Kasper Schmeichel has joined Nice, ending his incredible spell with the Foxes.” Following news of the goalkeeper’s departure, manager Brendan Rodgers appeared to confirm he would not be signing a replacement
