Chelsea have expressed an interest in signing winger Jürgen Damm from Pachuca, the Mexican club’s vice-president has revealed. The 21-year-old Damm was previously linked with Manchester United and underwent a trial with the Red Devils in early 2013. However, Andres Fassi says that Chelsea representatives could arrive in Mexico as early as Thursday to thrash out a deal. “Yes, there is interest but we have to see how much they are interested,” Fassi told Medio Tiempo. “In principle we have a sporting plan for Jürgen and we hope he stays, but if something comes up from abroad, we have to take it into account and if it’s serious, we have to respond, we will have news in the next 48 hours. “Chelsea are the club interested, but we have to see how much they are interested, we can’t go ahead of ourselves, we have to wait and see. “When it comes to us, it’s a matter of sporting project. We want him to stay and we will see how much Chelsea are interested. “There is a belief they arrive in Mexico on Thursday to talk with us.”
