Damien Comolli admits frustration being forced out of Liverpool.
The Frenchman oversaw £110 million in transfer spending during his time as football director.
"I still struggle a lot to watch Liverpool. I'm frustrated and annoyed because I feel there is unfinished business," he told the Daily Express.
"When you look at the economic situation that the leagues in Spain, Portugal, Belgium and Holland are in, it is very tough.
"With their new TV rights deal the Premier League is going to absolutely take off and leave everyone else behind, except maybe Germany. The future is very much here."
