Former Aston Villa captain Gabby Agbonlahor has slammed Liverpool boss Jurgen Klopp over his swipe at Didi Hamann.

Speaking prior to Liverpool's Champions League match against Rangers on Wednesday night, Klopp sarcastically hit back at Hamann after he claimed his fellow German's days as Anfield boss are numbered.

Now Agbonlahor has had his say, claiming that Klopp's sarcastic jibe is proof he is "losing it" and "cracking under the pressure".

"I thought Jurgen Klopp was like a petulant child," Agbonlahor told talkSPORT Breakfast.

"Didi Hamann won the Champions League for Liverpool, had a fantastic career, if he can't talk about Liverpool then who can?

"Is it only Robbie Fowler, Ian Rush, Steven Gerrard, is it only certain players who can talk about Liverpool?

"I think he's losing his spark a bit Jurgen Klopp, he's cracking under the pressure."
