West Ham United has delivered a body blow to Manchester United's transfer plans, as the club's new de facto owner, Daniel Kretinsky, is determined to keep Crysencio Summerville at the London Stadium. The Dutchman has been in impressive form at the World Cup, attracting interest from several top clubs, including Manchester United and Real Madrid. However, Kretinsky is keen to preserve the core of the current squad, with Summerville and Jarrod Bowen seen as key players in the club's bid to bounce back to the Premier League at the first attempt. West Ham United's valuation of Mateus Fernandes has been a major stumbling block in negotiations, with the club demanding a significant fee for the Portuguese midfielder. According to sources, Kretinsky is prepared to cash in on Fernandes, but only if it means retaining the likes of Summerville and Bowen. The club's new owner is determined to avoid a mass exodus of players, and is confident that he can persuade Bowen to stay if the club resists the temptation to sanction multiple high-profile sales. With the transfer window in full swing, West Ham United's fans will be eagerly awaiting news of the club's transfer plans, and whether Kretinsky can deliver on his promise to keep the club's key players. The future of Crysencio Summerville remains uncertain, but one thing is clear - West Ham United will not let him go without a fight. The club's determination to keep their star players is a sign of their ambition, and their desire to return to the top flight of English football. As the transfer saga continues to unfold, one thing is certain - West Ham United will do everything in their power to keep Crysencio Summerville at the club.
