Let's make this birthday one to remember.

73 years old (Born on March 01, 1952)

Happy Birthday, Martin O'Neill! From masterminding victories on the pitch in your Northern Ireland days as a legendary midfield magician (1971-1984), to steering Ireland famously into Euro 2016 knockout stages after taking charge in 2013—you've always mixed strategy with that witty charm. We still chuckle every time we picture your animated sideline antics; nobody juggles tactical genius and comedic theatrics quite like you!

So here's hoping this year brings many moments as memorable as beating Italy at Euro 2016 or navigating those nail-biting playoffs with pure style. May your team sheets continue being brilliant, and may referees go easy when you're passionately protesting decisions—just because it's your special day!
