Former Liverpool chief Damien Comolli stands by his work at Anfield.
The Frenchman oversaw £110 million in transfer spending during his time as football director.
“First of all, you need to look at the big picture,” he told the Daily Express.
“We did 26 deals and to think we wouldn’t make any mistakes in such a huge number of deals in and out would be totally unrealistic.
“I do not think we made any mistakes on the players going out and whether we made mistakes on the players who came in, time will tell. I am very uncomfortable for players to be judged after six, eight or even 12 months. Sometimes it takes two or three years.
“In two or three years you can say, ‘Damien and Kenny, you were wrong’. Or you can say, ‘They just needed time’.”
