Liverpool have lost a number of their best players in recent years.

Last summer saw the departure of Raheem Sterling to Manchester City, while the summer before saw Luis Suarez head to Barcelona.

In seasons gone by, the Reds have also lost the likes of Fernando Torres, Xabi Alonso and Javier Mascherano.
Klopp told the Liverpool Echo: “There hasn’t been a successful team in world football who change their squad every year. You need to need your key players. That’s a very important thing.
“You have to create a situation where you are successful. A situation where everyone feels in a good way and we are strong enough and patient enough to keep them together.
“We say that same squad and consistency creates success."
The Reds have kept hold of their key players from last season and barring some dramatic twist between now and the end of the transfer window, it looks as though they will remain for the season ahead. Many feared that Philippe Coutinho could have been the next to depart this summer.

They have, however, made several changes to their squad. Much of the starting XI for many of the Reds bigger games last season remain in some capacity but many players have left. Joe Allen, Jordon Ibe and Brad Smith are among those who have departed while seven new faces have arrived at the club during the summer.
But the club has had problems with their better players wanting to move on and achieve ambitions elsewhere. It's one reason why Liverpool have to improve on the field so that their best players believe they can achieve all the success they want to, and potentially attract even better talent in the process.
Liverpool showed last season that they were nearly there in terms of winning silverware and returning to the Champions League in the process, but without European football this season, they will want to put all of their energy into ensuring they have something to show for it by way of qualifying for the competition, or ending a five-year wait for silverware.
