Chelsea representatives will fly to Mexico this week in the hope of securing the club's first signing of the summer in the form of Pachuca winger Jurgen Damm.
The 21 year old has scored three goals and made three assists for the Liga MX side in the 2013/14 campaign and is understood to have attracted interest from the Blues.
And club vice-president Andres Fassi says Chelsea officials will travel to Mexico later this week in order to firm up their interest and clinch 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 Jurgen 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," he added.
"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."
With Damm possessing duel Mexican-German nationality he won't require a work permit in order to sign for the Premier League side, who are yet to start their transfer activity despite being linked with a host of high-profile players.
Atletico Madrid forward Diego Costa and Barcelona midfielder Cesc Fabregas have both been heavily linked with a move to Stamford Bridge following a season during which manager Jose Mourinho continually complained over the options available to him.
The club finished third in the Premier League and reached the semi-final of the Champions League but a number of big-name additions will significantly raise expectations ahead of the new season.
