Arnesen, like everyone at Chelsea, is excited about the talent of McEachran.
He said: "This summer five players came into the first-team squad - Daniel Sturridge is now 21, so he's the oldest of the younger talent. Also there is Jeffrey Bruma, Gael Kakuta, Patrick van Aanholt and Josh McEachran.
"I've watched Josh since he was 12, when I came here. I've followed him and saw then he was a big, big talent. But you never know how far it goes...how will a player cope when he gets up to the youth team?
"He did some very good things on tour in pre-season and maybe in half a year we will have to consider him going on loan, probably a little bit sooner to a Premier League club than Sturridge or Kakuta."
