Even Messi regrets skipping English as a kid.

Lionel Messi has admitted he regrets choosing not to learn English at a young age 🥺🏴
😖 “I regret many things,”
❌ “To not have learned English as a boy. I had the time to have at least studied English and I didn’t do it. I deeply regret it.” he told Mexican podcast ‘Miro de Atras’ back in February
🤝 “I experienced situations where I was with incredible and spectacular personalities to be able to talk and have a chat and you feel half ignorant. “I always thought: ‘What an idiot, how I wasted my time.’”
👦 “When you’re young, you don’t realise it. Today that’s what I tell my children, having a good education, to study and be prepared.
🧑🧑🧒🧒 “I always tell my children to take advantage of it. They have a different situation to the one I had although I never lacked anything...”
