Torres became the Premier League's most expensive signing ever at the time in January 2011.
And he's now revealed why he felt he had to end his stint at Liverpool.
Torres told BBC Sport: "Talking about [Antoine] Griezmann, I was in that situation where I wanted to be the best and I wanted to go to a team who give me the tools to become the best.
"The situation was different because when Rafa [Benitez] left and [Javier] Mascherano left and [Xabi] Alonso left, all the promises the owners made to the team were not true.
"I had everything at Liverpool. But then they sell the best players, the manager. So I had to find my own way.
"We were not building a team to win. That was the reality, the situation changed very much in six months."
