Today, 2 years ago, Mertesacker held a farewell match in his hometown of Hannover and officially announced his retirement!
Mertesacker said: "I will remind myself when I was young, you have to use your strengths, to grab the header, to compete for the top, to pass the ball simply and neatly. This is what you should do."
"Never forget your friends, and don't forget where you came from. These have made you who you are today. You have to learn to deal with differences and troughs, and always remember that football is your love and your greatest hobby. My achievements come from I am proud of my future self by accumulating bit by bit, being strict with myself, staying focused, and willing to accept new things."
