Tottenham are already on the back foot this summer, with four transfer targets slipping through their fingers just as the window officially opens.The summer transfer window is expected to open earlier than usual ahead of next season, which means teams can complete their transfers early.Looking on from the outside, Tottenham look far from ready for this window, as Spurs are yet to decide on the future of the man in the Spurs dugout, with a decision expected in the coming weeks.Yet, Spurs continue to be linked with several players ahead of the summer window, but reports suggest that they have already got off to a bad start, with four of their targets reportedly heading elsewhere. Here are the four blows handed to Spurs as the summer transfer window opens.Photo by SpursWebChelsea beat Tottenham to Liam DelapTottenham Hotspur have been linked with a move for Ipswich Town forward Liam Delap long before now, with reports suggesting that the forward was firmly on Spurs’ radar.In fact, with Richarlison said to be considering his future at Tottenham, the expectation was that Spurs would at least put in a bid to try to sign Delap, who impressed last season, scoring 12 goals for the Tractor Boys.However, that was not the case, as Fabrizio Romano has now given his “here we go” seal of approval to Delap’s move to Chelsea, after the Blues paid his £30 million release clause.Johnny Cardoso rejects Spurs for Atletico MadridGiving credit where it is due, it was a brilliant piece of business by Tottenham when they managed to secure a buy option clause for Johnny Cardoso in the deal that saw Giovanni Lo Celso move to Real Betis two summers ago.£21 million for a player who has impressed this season, leading Betis to a top-six finish, while also putting up a good show in the first half against Chelsea in the Conference League, Tottenham fans have already started to dream.However, it has since been revealed that Cardoso is not keen on a move to Tottenham, with Atletico Madrid said to be pushing for a deal as they look to strengthen their midfield.As it stands, it is reported that Tottenham will not exercise their option-to-buy clause for the USA international, who is reported to have already made it clear that his priority is to join Atletico.Rayan Cherki opts for Manchester City move over TottenhamThe blows keep coming for Tottenham before the opening of the summer window, as new reports now suggest that Rayan Cherki, who impressed last season, now wants Manchester City.Tottenham have been linked with Cherki, who grabbed eight goals and 11 assists in Ligue 1 for months, and Spurs were even labelled as favourites to land Cherki by some outlets.However, it has now been reported that Rayan Cherki has given the green light to a move to the Etihad, with a bargain deal of £33.7 million set to be wrapped up before the Club World Cup campaign begins.Leroy Sane in talks with Bayern Munich despite Tottenham interestEarlier this week, it was revealed that Tottenham have been offered the chance to sign Leroy Sane from Bayern Munich, with the winger set to become a free agent this June if he does not agree a deal with Bayern Munich.It was reported that negotiations between Sane and Bayern had hit a roadblock, as both sides were failing to reach an agreement.Daniel Levy was said to be open to a move for Sane, as he reportedly has a good relationship with the player’s agent. Spurs were even tagged as Leroy Sane’s preferred destination, as it was revealed that he was open to a move to the Premier League, north London in particular.However, another blow has been handed to Tottenham regarding the Sane deal, as the winger and Bayern Munich are now advancing in talks, with the feeling being that a deal between the two sides would be reached soon.READ MORE: Tottenham Supporters Trust make strong demands to Daniel Levy this summerThe post Tottenham suffer quadruple transfer window blow as Daniel Levy twiddles his thumbs appeared first on Spurs Web.
