Video shows Lionel Messi playing football with 11-year-old British boy on a beach. Anna O’Neill filmed her son Mackenzie playing with the Barcelona forward. Three other children also joined them, including Messi’s son Thiago. Anna revealed later that she was ‘humbled’ after Messi played with her son. “It was such a sweet experience. They’re just a very normal family,” Ms O’Neill told PA.
