Let's make this birthday one to remember.

40 years old (Born on September 29, 1984)

Happy Birthday, Per Mertesacker! The man whose defensive skills were as towering and reliable as his height. Arsenal fans still fondly recall your legendary FA Cup final performance in 2017—when you defended like a fortress against Chelsea, proving once again that you're the ultimate "BFG" (Big Friendly German).

Now retired from playing but thriving at developing young talent for Arsenal's academy—you've swapped clean sheets on matchdays for nurturing future stars every day. May this birthday bring fewer stressful moments than marking speedy strikers—and more cake slices taller even than yourself!

Cheers to another year of greatness, BFG!
