The German driver would retire agin after this season. He said, "I can be happy with my performance and the fact that I was continuously raising my game, but then, at some point it is time to say goodbye. I had a lot of criticism in the past three years which partly was justified. We didn't achieve our goal to develop a world championship-fighting car."
Schumacher is without a win since returning and so far this year he's 12th in the championship standings with only one top-five finish in 14 races.
He's 43 year-old, I guess this is his final goodbye. He was a great champion and even tough many people didn't like him I really enjoyed waching him race.
