Manchester United legend Gary Neville says this season has been a learning process for the club's youngsters in Europe.
Neville thinks this season has been a steep learning curve for United's young stars.
The former England right-back said: "The only way you learn European football is by playing and getting to the point where you start to absorb lessons.
"The younger players in our squad will take a lot out of this season.
"There is a subtlety and attention to detail you need in Europe.
"Inches matter and whereas the Premier League can be a little more forgiving, in Europe opponents are more ruthless and more clinical in front of goal.
"I remember it when we were young lads too. It's just something you have to go through.""The manager knows he's got talented young players who are going to be at United for a number of years, and I think this year has almost been a step back to go forwards in Europe.
