Moreno’s partner gave birth to a baby boy - Alberto Moreno Junior - at around 2.30am, with the full-back at Liverpool’s team hotel in the city centre.
The Spaniard remained with the squad and duly turned in an outstanding display in Liverpool’s 3-0 win over Southampton at Anfield.
Klopp told his post-match press conference: “Alberto Moreno is a father!
“At 2.30am in the morning, his wonderful girlfriend gave birth – Alberto Moreno Jnr was born in Liverpool.
“He was in the [team] hotel [when he was born]… sorry!”
