Carlo Ancelotti gave him his first-team debut as a Champions League sub away to MSK Zilina last September and a number of other appearances from the bench followed.
But as Chelsea's season fell apart, McEachran disappeared from view and did not return to the side until they were already out of Europe and the title race.
He confessed to The Sun: "It was a frustrating time for me. The team was going through a difficult spell and I wanted to contribute and be a part of things.
"But Carlo was under a lot of pressure at the time and I could see why he preferred to use the experienced players rather than the likes of me and Daniel Sturridge.
"When you're with a club as big as Chelsea you are always competing for a place in the team against world-class players so you know you have to be on their level just to get a game.
"It does need a lot of patience but I prefer to be with a top-class club and training with world-class players every day.
"I do feel much more a part of things under Andre Villas-Boas. He gave me a lot of minutes on the pitch during our pre-season games and hopefully I can keep doing that."
