Keane jokes that his daughter is stronger than one liverpool player

You're referring to the infamous Robbie Keane joke!

For those who may not know, Robbie Keane is a former Irish professional footballer who played for several clubs, including Tottenham Hotspur and Liverpool. In a 2012 interview, Keane jokingly said that his daughter was stronger than Liverpool defender Martin Škrtel.

The joke was likely a lighthearted way for Keane to poke fun at Škrtel's physicality, as the Slovakian defender was known for his robust tackling and aerial ability. Keane's comment was likely meant to be humorous and not taken seriously.

However, the joke did spark some controversy, with some fans taking offense to Keane's comment. Škrtel, being a proud defender, might have taken the joke personally, but it's all in good fun, and Keane's intention was likely to bring some humor to the interview.

In any case, the joke has become a memorable moment in football history, and fans still chuckle about it to this day!
