Chelsea are reportedly eyeing a triple swoop for Jadon Sancho, Moussa Dembele and Jude Bellingham as part of a big-money summer splurge.
The Blues failed to add to their squad in January and boss Frank Lampard recently admitted that his team "lost ground" in the last two windows.
However, Lampard's side agreed a deal for Ajax attacker Hakim Ziyech on Thursday that will go through in the summer and is worth up to £36m.
According to the Daily Mail, plans are already in place to bring in three more players ahead of next season.
Borussia Dortmund winger Sancho, Lyon striker Dembele and teenage Birmingham City midfielder Bellingham are the players said to be on Chelsea's radar.
All three are in demand, though, with Manchester United and Liverpool believed to have made their interest known in Sancho.
