Chelsea are close to completing a deal for Manchester United target Juan Familia Castillo from Ajax, according to reports from the Daily Mail.
The 16-year-old previously held talks over a switch to Old Trafford, but looks to have now been persuaded to make a move to Stamford Bridge.
Given their form this season, the Blues are set to undergo a squad overhaul as they currently find themselves struggling in 10th place despite winning the league title last term.
The Daily Mail have claimed that the deal is set to be confirmed in the coming weeks, with the midfielder expected to join the youth ranks with the English giants.
With the club having already announced a move for Italy boss Antonio Conte to replace Guus Hiddink this summer, a number of new faces are expected to be brought in as well.
Aside from Castillo, the Blues are also eyeing a sensational deal for Atletico Madrid star Antoine Griezmann.
