Italian coach Carlo Ancelotti expects it to take a couple of years before the likes of Manchester United make an impact in the Champions League again.
As reported by Goal.com, the ex-Real Madrid boss believes that United's investment in youth will hinder them as they go in search of immediate success in Europe's elite competition.
English sides have struggled on the European scene recently, but Ancelotti claims that a number of teams are in a period of transition as they go about overhauling their squads.

In fact, out of all the English sides in the competition, the experienced coach believes only his former club Chelsea are equipped to compete for the big-eared trophy this term.
Ancelotti told Goal: "The reason for the decline is that the big English sides have overhauled their squads a lot, apart from Chelsea, who have experienced players and leaders.
"The others, like Manchester United, have taken young players of less experience. Therefore, they have revamped their sides and there have been difficulties. They must wait a couple of years to be competitive in Europe again."
It's difficult to disagree with Ancelotti's comments on United. Under Louis van Gaal, the Old Trafford outfit are still a work in progress, but will eventually come to prominence in their pursuit of success.
With Anthony Martial, Memphis Depay, Andreas Pereira and Co. all starring at the Theatre of Dreams, United fans will be eager to see their crop of young stars develop sooner rather than later.
However, the Red Devils faithful may well have to be patient; the Manchester giants are on their way up, but still have some way to go before reaching previous great heights.
