Tuchel added: “I’m superstitious too, I can understand why players might not touch it and have other preferences. It’s kind of like that, but I think Raheem will help us a lot and in general it’s our responsibility to create more attacking positions to maybe have a bit more players in the box.” Chelsea have completed the signing of left-back Marc Cucurella for £55m, plus £7m in add-ons, and, despite Leicester City’s insistence that he is not for sale, have not let go of centre-back Wesley Fofana, who they have. he made more than one bid and believes he wants to move to Stamford Bridge. There have been talks about midfielder Frenkie de Jong, who Chelsea believe will join them for Manchester United if he decides to leave Barcelona. Cesar Azpilicueta has signed a new two-year contract but Tuchel has confirmed he would still like to sign another defender, even though Chelsea may have to pay more than £80m for a defender to land Fofana. Tuchel said: “Azpi and Trevoh Chalobah play in the same position in the back three, Marc can play in the back three on the left. Kalidou (Koulibali) can play in the three on the left and we have Thiago Silva who unfortunately is not getting any smaller. So maybe we bring in a player, maybe not. Let’s see if we can make another signing.” Teenage defender Levi Colwill has joined Brighton on loan and Chelsea have discussed finding a deal for Werner to return to RB Leipzig and Kepa Arrizabalaga to join Napoli on loan. Cucurella, who has signed a six-year contract at Chelsea, said: “I am very happy. It’s a great opportunity for me to join one of the best clubs in the world and I will work hard to be happy here and help the team.” Co-owner Todd Boehly, who is interim sporting director, added: “Marc is an elite defender of proven Premier League quality and further strengthens our squad going into the new season. We continue to work on and off the pitch and we are delighted that Marc will be part of the present and future at Chelsea.”
