Chelsea manager Frank Lampard says his side are a 'long way' off catching Liverpool and Manchester City.
The Blues have already made moves for next season by signing Timo Werner and Hakim Ziyech, with Kai Havertz reportedly close to arriving from Bayer Leverkusen.
But Lampard says it is consistency which separates his side from the Premier League's two current heavyweights.
Asked how far off his side from the consistent standards of Liverpool and Manchester City, Lampard said: "A long way.
"We have to be realistic about that as a club, as do many of the other clubs, because themselves and Manchester City, particularly Liverpool this year, have shown an incredible consistency that only comes through hard work and time with fantastic players and fantastic coaching.
"We are at a different point in the curve. You are talking about probably the two best club teams in world football, up there with a couple of others in European football.
"The points don't lie over the past few seasons. We are realistic but we have targets and we want to close that gap."
